Blackberry

Common Names: Blackberry

Latin Name: Rubus sp.

Spanish Name: Zarzamora

There are 11 different species of wild blackberry in the state of California. Himalayan Blackberry (R. discolor), one of the more common and fruitful in California, exhibits five leaflets that are oval shaped and toothed. Thimbleberry blackberry (R. parviflorus) is the only one of the four weedy blackberries that is non-thorny and non-vining and has a simple leaf as opposed to multiple leaflets. Cutleaf blackberry (R. laciniatus) has five leaflets that are rounder and lobed. California blackberry (R. ursinus) has three leaflets. These brambles grow as vines and produce a sweet blackberry. Himalayan blackberry and Cutleaf blackberry are non-native weeds, whereas California blackberry and Thimbleberry are native, but are considered weeds in certain conditions. The best time of year to collect wild blackberries is in July and August, but plants will differ in the times that they are ripe. To harvest, simply pick the ripe blackberries off the plant, while being cautious of thorns. The plants can live upwards of 25 years, and the spread of their seeds is facilitated by the many animals that eat them.

 

WARNINGS: Thorny Stems; Poison Oak can look similar to Wild Blackberry: it has three leaflets that are ovular and have lobed margins, and are shiny green in summer, turning shiny red in fall. To tell them apart, blackberry usually has thorns on the vines and fuzzy leaves, poison oak should have neither.

Location in IV/Campus: Various locations in open spaces; massive bush by the FT side of Santa Ynez housing; in the Camino Corto Open Space by the little bridge and spread through the trees

Bluedicks

Common Names: Bluedicks, Blue Dick, Wild Hyacinth

Latin Name: Dichelostemma capitatum

The Bluedick is a native, spring perenial of the west coast of North America from Oregon to Baja, and as far east as Utah, that springs up from a edible bulb or corm.  It can be found from sea level to 7000 feet throughout most of California, and commonly found in sunny, grassy places and after disturbances. The leaves are very long and narrow, and hug the tall, central stem of the single flower stalk that is tipped by a cluster of blue-purple flowers of six petals that meet in the white and yellow center. The leaves can smell onion-y when crushed. To harvest the corm, keep in mind you should wait until the plant has fully died back for the winter. The corms were a good source of starch in many indigenous diets, either raw, ground into flour, or cooked slowly for sweeter flavor; they were planted in wild gardens, dug up with digging sticks and were known to be eaten more often than acorns by some groups. The flowers are also edible. Gardeners say that these plants are relatively easy (in comparison to other CA bulb plants) to grow from bulb and seed if you want to start a native garden!

Chickweed

Common Names: Chickweed

Latin Name: Stellaria media

Spanish Name: Pamplina

For gardeners the world over, chickweed is unwanted and hard to get rid of, but to the avid forager, it’s a mild, tasty spring snack! This invasive Indo-European plant grows as a thick, sprawling ground cover in damp, mostly shady places, usually in areas that have been regularly disturbed by humans. The leaves are rounded tear drops, bright green and no bigger than the nails on your smaller fingers; these leaves grow in pairs that alternate (north-south pair on top of an east-west pair). The small white flowers have five deeply lobed petals that may appear to be ten very small petals. And most importantly, this plant has a very fine line of hairs down one side of the stems (IT MUST HAVE THE LINE OF HAIRS OR IT IS NOT CHICKWEED). You should also be able to gently pull the stem apart and the outer layer of the stem will separate while the inner layer should stretch out. Chickweed purportedly has vitamins A, B, C and D, the elements Ca, K, P, Zn, Mn, S, Cu, Fe, Si (it is comparable with spinach in nutrient content) and has been used in traditional medicine to help with inflammation, digestion, bad skin, and to restore those recovering from bad illnesses, amongst other uses.

WARNINGS: If the plant you’re looking at has red or orange flowers, OR seeps a milky white fluid, OR doesn’t have flowers, it is NOT the right plant--DO NOT EAT IT; Spurge and Scarlet Pimpernel are poisonous look-alikes.

Location in IV/Campus: these plants can be found in many places, especially where it is damp and where you can find other annual weeds

Fig

Common Names: Fig

Latin Name: Ficus carica

Spanish Name: Higo

Common fig can be easily identified by its large dark green leaves, spanning 10 inches long and 5 inches wide, identified by its greenish, brownish or purplish pear shaped fruit of size 2-4 inches. Each leaf has a deeply lobed shape with between three and five lobes per leaf and are thick and leathery with smooth sides. The Common fig tree can grow up to thirty feet with smooth white bark and droop often as they grow. This tree is native to the Middle East and Mediterranean region. Interestingly, the Fig tree has it's very own symbiotic relationship with the Fig wasp (Agaonidae) who does most of the tree's pollination. Figs are highly nutritious fruits, containing vitamins such as A, E and K all of which aid with vision, skin and blood pressure, respectively. Figs are also high in fiber, which aid digestion and control blood sugar. Figs are great for snacking raw, smoothie bowls, and toppings for yogurt! 

 

WARNINGS: Fig fruit is safely edible, but fig leaves are not in high doses. Fig leaves are also generally advised to not rub on skin due its high latex content and milky sap. For this reason it is advised to rinse the fruit before ingesting. Not all figs are edible, weeping fig (Ficus benjamina), for instance; always make sure to ID the plant before ingesting.

Ice Plant

Common Names: Ice Plant

Latin Name: Carpobrotus edulis

Spanish Name: Doca

Iceplant is a robust perennial succulent shrub that is native to coastal South Africa. The plant is abundant and considered an invasive species on California’s Mediterranean coast in which it thrives. The plant grows in a thick and dense mat-like way. Its thick succulent stems grow horizontally and curve upwards. Flowers generally appear in late winter to spring and can be yellow, pink, and  purple. The ice plant’s fruit appears once the flower dies back and is edible. The fruit is yellow and fleshy when ripe and resembles a fig or spinning top. Hypothetically,  the flavor is salty and sour, mildly sweet when riper; a taste test showed us that the flavor is very bitter and an unpleasant aftertaste persists for some time. Early spring in California regions is the best time for collection. Simply pick the fleshy fruit (resembles a spinning top), it will be yellow in color when ripe and can be eaten fresh. The outer layer is astringent and is ideally removed before eating the more jelly-like interior, where the seeds are located. Ice plant was introduced in California during the early 1900s for coastal erosion mitigation; the plant still outcompetes many native coastal plants to this day. Ice plant can inhibit the natural movement processes of sand dune environments. In South Africa the ice plant’s fruit is sometimes referred to as a sour fig.

WARNINGS: Ice plant grows along bluffs and steep coastal cliffs, as well as all throughout IV. DO NOT harvest ice plant close to cliffs.

Mugwort

Common Names: Mugwort

Latin Name: Artemisia douglasiana

Chumash Name: Molush

Mugwort grows to be 7ft tall, but is usually about 4ft tall. The stalks are erect with few branches. The leaves are about four inches long, oblong and divided into at 1-7 lobes. Above the leaves are dark green. Below, the leaves are white from many hairs. Flowers are very small and are hidden by dense leaves. The plant leaves have a very pungent sage smell and bitter taste. Mugwort is found from Baja California to Washington and Idaho and tend grow in riparian corridors and can be found in dry or moist shaded areas and on a variety of soil types. Mugwort is a cleansing herb and highly medicinal with many uses: the leaves can be chewed on but spit out to relieve tooth pain, the leaves can also be used as a hand sanitizer by simply rubbing the hands together with the leaves. Culturally, mugwort leaves and stems are placed under a sleeping pillow to keep evil spirits away and promote good dreams, and have been burned as smudge sticks for energy cleansing. Some indigenous groups would rub their bodies with mugwort after someone died so they would not be haunted. Because dried mugwort is an amazing source of tinder, this plant was used to start fires and even cauterize wounds. Mugwort is best used as a tea for premenstrual, menopausal syndrome, hot flashes, and dysmenorrhea. Use only one leaf, do not add any sugar and drink only one mug a day. Crushed leaves can be rubbed directly onto the skin or made into a wash to prevent and clear up poison oak rashes.

WARNINGS: Mugwort contains many active compounds such as cineole, camphor, linalool and thujone which can induce convulsions and renal damage if ingested in large doses. The recommendation is to use a single leaf to avoid any harmful effect. They tend to grow, albeit conveniently, near toxic plants like poison oak. Mugwort should NOT be consumed by pregnant woman. Be aware: Ragweed is a look-alike that causes extreme cases of hay fever.

The flesh and skin surrounding the seed of the fruit is edible and has a sweet and tangy pineapple-tropical flavor; it is unique to most fruit you have probably tried. The flesh is very fibrey and juicy. The fruits are a good source of carotene and can be used to make jams, jellies, and juices.

WARNINGS: The fruit has a large seed inside; be careful not to bite down with too much force or swallow the whole fruit.

Location on campus: In front of the arts building on the gravel, grass, and bordering the bike racks.

Pineapple Guava

Common Names: Pineapple Guava

Latin Name: Feijoa sellowiana

A flowering tropical evergreen shrub or multi-trunk tree with shiny foliage and white undersided ovular leaves. Stands between 18-25 feet tall and wide. The flower has a sweet pineapple, apple and minty fragrance and looks like a bright pink firework with pink hairs in the center of 4 white to purple-tinged, curled petals. The flowers and fruits are edible. The fruits are light to deep green, round to oblong with a 4-pronged obtrusion opposite the stem. The fruit is safe to eat whole and raw; the skin is tough and bitter but the inside is sweet and almost gooey with small edible seeds. Pineapple guava fruit season is early November to December but can last until early Spring depending on the area. Ripe pineapple guavas will fall to the ground. It has been used in salads in South America, along with chutneys and deserts. The feijoa has no known medicinal properties, but it is sometimes used as a digestive aid and cosmetic exfoliant, and its skin has been studied for its antibacterial properties. This tree is native to native to Southern Brazil and attracts bees, squirrels, and birds. The fragrant aroma is due to the ester methyl benzoate compound in the fruit.

WARNINGS: None.

Pineapple Weed

Common Names: Pineapple Weed, Street Weed, False Chamomile

Latin Name: Matricaria matricariodes

Spanish Name: Hierba de piña

Pineapple Weed is a low growing plant with fine, feathered leaves, and smells of pineapple when crushed. The flowers are small, yellow, composite cones without petals. It grows in many places in both polar hemispheres, typically where the soil is dry, disturbed and otherwise unpleasant for many other plants. The flowers and leaves can be eaten raw or in tea; the flowers can be dried out and ground into flour. It has similar properties to its cousin, Chamomile: helps with relaxation, sleep, digestion and colds. It can also be used as an insect repellent.

WARNINGS: It looks similar to Chamomile, Mayweed and Dog Fennel, although when crushed, Pineapple Weed smells like pineapples. Try to harvest it in places where dogs and chemicals can’t reach the plant. Some people are allergic to this plant.

Location in IV/Campus: These plants can be found most places in Isla Vista and in some weedier areas on campus.

Recipes: Tea, Cookies, Jam

Plantain (Narrow & Broadleaf)

Common Names: Narrow and Broadleaf Plantain

Latin Name: Plantago lanceolata, Plantago major

There are two types of plantain found on campus, the broadleaf and narrowleaf.  The leaves are rounded with a point on the end and have slightly jagged or wavy edges. Leaves are usually arranged in a basal rosette, even more commonly with the stockier broad leaf plantain.  They have 5-7 parallel leaf veins with a rough texture on both sides and a fibrous root system. When flowering in late spring-fall, plantain grows a long, 8in stalk with tiny flowers. The ripe seeds from this stalk can be collected, ground and made into a flour. The leaves are edible and are best picked when they are young for salads.  Older leaves can be soaked in salt water for 4 minutes and cooked like spinach. Broadleaf plantain also has medicinal uses. It can be chewed and placed on stings, cuts or poison oak rashes to ease inflammation.

WARNINGS: None.

Location on campus: All around IV and campus in lawns (broad leaf), weed patches, disturbed sites, lagoon island (narrow leaf).

Prickly Pear Cactus

Common Names: Prickly Pear, Cactus Pear, Indian Fig

Latin Name: Opuntia spp.

Spanish Name: Nopal, Tuna

The prickly pear cactus is a common name for the genus Opuntia which represents many varieties of prickly pear cactus, including beavertail and Santa Rita cactus. The cactus is native to the United States and South America but can be found around the world. The cactus has fleshy, flat oval pads, called pencas in Spanish, with defensive spines and smaller glochids, or hair-like spines. The varieties can grow up to 20 feet tall. The pads produce bright and brilliant flowers from late spring to early summer that range from yellow, orange, pink, and red. The flowers grow on the tip of the cactus pads and can grow up to three to four inches wide. After the flower has finished blooming, the prickly pear fruit, or tuna in Spanish, form. The edible fruit is pear shaped and varies in color from green (less sweet) to red (very sweet). The fruit has a sweet taste and the taste changes depending on variety of prickly pear. Many have described the flavor of a prickly pear fruit as melon, strawberry, watermelon, or citrus. Harvest prickly pear fruit anytime from early Spring through late Fall. The pads of the prickly pear are edible and taste like green beans. The younger, greener pads are often harvested and eaten as they have the fewest spines and are more tender. Some Native Americans used the fruit to make candy and chewing gum. Native Americans used the sap from the pads on cuts, burns, and bruises to soothe the wound. Traditionally, the young pads can be used as a laxative and can be used to treat diabetes.

WARNINGS: Be careful of spikes and glochids or the pads and fruit. Glochids will easily fall off from the cactus and imbed in skin and cause irritation.

Location in IV/Campus: Can be found near Fortuna behind the Camino Corto Open Space

Sour Grass

Common Names: Sour Grass

Latin Name: Oxalis stricta

This common perennial has yellow flowers with five parts and can grow up to 50-100cm in height. Leaves are alternate and form three heart shaped leaflets, much like a three leafed clover. We have observed the plant to bloom during the rainy season when it begins to warm up; it needs a lot of water. Pick leaves, flowers or stems to chew on. Tastes sour, but in a pleasant way, although can occasionally be extremely tart. Oxalic acid gives the plant its sour taste. A yellow-orange dye can be made of the plant by boiling it.

WARNINGS: Oxalic acid is toxic in large doses

Location on campus: Found in newly disturbed, wet areas like fields and planters that have gone wild.

Recipes: Sour Apple Spritzer; We made a raspberry flavored tea by soaking chopped stems in boiling water.

Strawberry Guava

Common Names: Strawberry Guava

Latin Name: Psidium cattleyanum

Spanish Name: Guaya fresa

The Strawberry Guava is a tree native to Brazil that belongs to the family Myrtaceae. The fruit of the Strawberry Guava is spherical, small (about 4 cm long), and red/purple in color when ripe. It has glossy, green, oval leaves and white flowers with five petals. The Strawberry Guava produces fruit year round. Trees on campus produce ripe fruit at different times depending on their location. To collect, simply pick the fruit off the tree. The fruit only lasts 1-2 days at room temperature. The Strawberry Guava is sweet, but also has a slight tang. The fruit tastes like its name, with flavors of strawberry and guava.  The fruit is high in antioxidants and has anti-inflammatory effects. The Strawberry Guava helps with digestion because it contains a large amount of fiber. It helps prevent scurvy because it contains Vitamin C. The Strawberry Guava is also known as cherry guava, purple guava, and cattley guava. Strawberry Guava is an invasive species on the Hawaiian Islands. It has invaded hundreds of thousands of acres on the islands and threatens to spread even more. Non-native pigs and birds facilitate its spread when they eat the fruit.

WARNINGS: Only eat the fruit of the Strawberry Guava, as it is the only part of the plant that is edible. 

Location on campus: West side of South Hall, South/East side of Harold Frank Hall, and Robertson Gymnasium.

Strawberry Tree

Common Names: Strawberry Tree

Latin Name: Arbutus unedo

The Strawberry Tree is a relatively short tree, 15 to 30 ft high. When mature, the fruit of the Strawberry Tree is spherical, small, red in color, and has a rough and bumpy outer layer. The texture is strange on the tongue. White bell shaped flowers grow in small clusters. The bark is a reddish-brown color that peels in the sun. The leaves are green, glossy and serrated. It is an evergreen and often used ornamentally. The fruit is the only part of the Strawberry Tree that is edible. The fruit is best to eat in Autumn, when the fruit matures. Simply pick the fruit off the tree. It has a sweet taste, and has flavors that have hints of strawberry and peach. May lower blood pressure and fight against colds. Contains tannins and Vitamin C. The tree is related to Manzanitas (aka refrigerator trees). The bark peels because it gets sunburnt! The Strawberry Tree is part of the Coat of Arms of Madrid. The Coat of Arms depicts a bear eating from a Strawberry Tree. The Strawberry Tree was mentioned by Ovid, a Roman poet from the first century BCE, in his work titled Metamorphoses. In Ireland the ballad “My love’s an Arbutus” correlates the strawberry tree and true love qualities

WARNINGS: Make sure to only eat the fruit on the tree. Under ripe fruit can cause nausea. Overripe fruit can cause intoxication

Location on campus: There are Strawberry Trees located on the South side of Broida Hall, on the South side of the Humanities and Social Sciences Building, in the Girvetz courtyard, along El Colegio heading West from campus towards Santa Ynez housing, as well as near Webb Hall. They are all over campus.

Recipes: Jam; To make the herbal tea, soak the Strawberry Tree leaves in a cup of hot water.  Other things like lemon zest can be added to improve the taste.

Wild Radish

Common Names: Wild Radish

Latin Name: Raphanus raphanistrum, Raphanus sativus

Spanish Name: Rabanillo

Wild radish is a common annual weed in the mustard (brassicaceae) family and is native to eurasia. The roots of the wild radish are edible, but are often smaller and less appetizing than radish from the grocery store. Leaves are lobed and tough, and grow off of a bristly stalk that grows up to two feet tall. The leaves can be eaten raw and cooked and are best collected when they are young. Its flowers are edible and have four petals up to about an inch long. Flower colors range from white, pink, purple, and yellow, and can exhibit a streaking pattern. Wild radish hybridizes with cultivated radish, contributing to the range of colors seen in its flowers. Spring and summertime are generally the best time to forage this plant. The seed pods of the radish are also edible. The pods grow off of the stem, have a long roundish shape, and are around one to three inches long and up to ¼ of an inch wide. 

WARNINGS: Try to avoid eating these in places where dogs could have urinated on them or where people are spraying pesticides.

Location in IV/Campus: Found in weedy fields intermixed with grasses, and other disturbed areas.

Fascinating Flora

UCSB campus has an astounding amount of botanical biodiversity thanks to a wide range of people from horticulturists and the environmentally minded, to home gardeners and restorationists. Each has had a unique hand in shaping the quirky, beautiful landscape that we see today. Some of these plants are in collections from specific continents, or are meant to reflect native California ecosystems, while still others mind the drought and require little water or were planted as part of the Edible Campus Project so students can get free produce. There are even hidden gems that to most just look like a nondescript plant but to the informed is a window into the mind of the botanist that planted it.

The wonderful Mediterranean climate of Santa Barbara also allows for a massive variety of plants to grow and reproduce, making this the perfect place for an exotic garden collection. UCSB is home to many rare and endangered species. Without further ado, let’s explore them!

Particularly Pulchritudinous Plants

Oddly enough the word pulchritudinous means beautiful! This campus is home to some of the most gorgeous plants you will see in California. I speculate this is because the school uses recycled water on the plants, which means that more water can be used without "wastage". Many plants need a lot of water to grow beautifully, which is why native plants in this state rarely have huge flowers or broad leaves (read: it rarely rains and we are constantly in a drought).

Bauhinia purpurea

Also known as the Orchid Tree, Butterfly Tree, and my personal favorites: the Camel's Foot Tree and Gorro de Napoleón (Napoleon's Hat). But don't let the name fool you! It is not actually in the Orchid family, but in the Legume family. This lovely plant is native to southern Asia. It has a potentially record breaking method of seed dispersal: it can shoot them as far as 49 feet from the parent tree! The bark, roots and flowers have been used in traditional medicines, not to mention many parts are eaten!

Senna pendula var. Glabrata

The misnomer Easter Cassia, or the more correct Winter Senna, are both common names for this lovely yellow flowering invasive legume. Native to tropical South America, but naturalized in many parts of the world due to its weediness, this showy plant is the bane of many experienced gardeners and the bell of Christmas-time landscaping in warm regions. Find this lovely plant in the courtyard between the Life Science and Noble Hall buildings.

Spathodea campanulata

Also known as the African Tulip Tree, Fireball, Flame of the Forest, Fountain Tree, Pickari, Nandi Flame and Squirt Tree; the latter name comes from the strange quality of how nectar can squirt from the flower if squeezed properly. The tree is native to tropical Africa (surprise surprise) and can reach 80 feet tall in its natural range, but is stunted in dry California. It is considered one of the world’s top 100 most invasive species; although this is only seen in wet areas. The flowers are considered “perfect,” which means they contain both male and female parts. The seeds of the yellow flowering tree are infertile and to a graft must be used from another tree to grow a new one. The flowers are a very interesting trumpet shape and the buds look like clusters of animal claws.

Eschscholzia californica

The Eschscholzia californica, known as California Poppy, as golden poppy, flame flower, copa de oro (cup of gold), among other names is a deep-rooted perennial and flowering annual plant native to the western United States. It is one of 11 species of poppies that naturally occur in the western United States. The flowers stun many with its brilliant orange, yellow, or cream hue and satiny petals. Native Americans used poppies for a myriad of purposes, including food and medicine. The roots were used as a sedative and analgesic and the petals chewed like gum or candy. However, the California poppy may be toxic when used without sufficient preparation.

Strangely Structured Stems

This section is about all the funky looking plants we have on campus. The wide variety of adaptations seen in plants exist for any number of reasons, and some times for no reason at all! Adaptations can assist in: attracting specific or general pollinators; attracting specific herbivores which will digest their seeds in a way conducive to germination; or scaring away or harming other herbivores; reacting to seasonal environmental disturbances such as fires or floods. There are many other reasons for traits in plants; you name it, some plant somewhere probably has that adaptation. Come explore some of the interestingly adapted plants we have on campus.

Agave attenuata

Also known as Foxtail, Swan’s Neck or Lion’s Tail Agave. They send their reproductive parts high into the air (10 feet) to protect them from herbivores. Bats are their biggest wild pollinator. Agave are succulents, much more closely related to the Asparagus family than the cactus family. These plants are monocarpic, meaning once they flower they die. Agaves are used to make tequila and syrup. Indigenous people to North America, the Hohokam and Navajo, used agave as food. Agave reproduce via ‘pups’ which are tiny plants the grow from the flower stock, rhizomes and along the main trunk of the plant.
