Santa Cruz Tarplant (Holocarpha macradenia)
Location: Arana Gulch

This rare and endangered plant endemic to Northern California is the reason we have Arana Gulch Open Space. The City manages the park in a way that promotes the success of this species. Adapted for disturbance historically common in coastal prairies, cows graze the landscape much like megafauna used to thousands of years ago.

California Poppy Maritime Variety (Eschscholzia californica var. maritima)
Location: Santa Cruz Museum of Natural History

The Garden Learning Center at the Museum features several habitats. The front garden is a coastal prairie featuring our local variety of California poppy in abundance! Our maritime variety has a darker center with light edges, whereas the standard poppy is more orange throughout.

California Buttercup (Ranunculus californicus)
Location: Santa Cruz Museum of Natural History

These bright, shiny yellow flowers often bloom earlier than many other species, and will go to seed and return to a dormant state by early summer. Buttercups can be a nice source of nutrition and can be toasted or ground up and added to baked goods.

Common Self Heal (Prunella vulgarus)
Location: Santa Cruz Museum of Natural History

In addition to attracting pollinators, this edible plant has long been used as a remedy for a variety of ailments, including sore throats and muscle aches. Some of its other common names include heal-all, woundwort, heart-of-the-earth, carpenter’s herb, and brownwort.

Gumplant (Grindelia stricta)
Location: UC Santa Cruz Coastal Science Campus

In the early stages of blooming, the head of this yellow aster produces copious white exudate (i.e. goo). Indigenous cultures have traditionally used this exudate as an adhesive.

Western Blue Eyed Grass (Sisyrinchium bellum)
Location: UC Santa Cruz Coastal Science Campus

Actually a member of the iris plant family, blue-eyed grass produces deep purple flowers in late winter and early spring. The genus name means “pig snout”, referencing the sweet roots that were dug up by pigs in their native grasslands.

Monterey Mariposa Lily (Calochortus uniflorus)

The genus Calochortus contains some of our region’s most sought-after flowers. This rare species has grass-like leaves and upright flowers shaped like a bowl, which bees often rest in. Featured here is a longhorn bee (Melissodes sp.)

Yellow Mariposa Lily (Calochortus luteus)

Another member of the Calochortus genus, this California endemic flower is more widespread than C. uniflorus, but can still require a bit of a hunt. Conveniently, this species pops-up right near the gate to Mima Meadow. Turn right on the first trail you see and make sure you don’t discount every bright, big flower as a poppy!

White Brodiaea (Triteleia hyacinthina)

Also known as fool’s onion, this plant has an edible bulb, though it lacks the familiar onion smell.

Harlequin Lotus (Hosackia gracilis)

This rare plant belongs to the pea family and is unlike any plant you’re likely to find with its mix of sherbet colors. It’s thought to be a larval food plant of the Federally Endangered lotis blue butterfly (Lycaeides argyrognomon lotis).

Sky Lupine (Lupinus nanus)

Our region hosts many types of lupines and they can be challenging to tell apart. Even when not in bloom you can identify a lupine by its palmate leaves (five fingered like a hand).

Golden Brodiaea (Triteleia ixioides subsp. ixioides)

This cheerful yellow flower is in the same genus as the white broadiaea and also grows from a bulb.

Ben Lomond Spineflower (Chorizanthe pungens var. hartwegiana)

You really have to see this flower in person to understand just how tiny it is. This rare member of the buckwheat family is found only in our local Santa Cruz sandhills habitat. You don’t have to travel far along the trail to find dense mats of this flower when in bloom.

Bush Poppy (Dendromecon rigida)

This shrub offers a pop of color to the Reserve when in bloom and can reach many feet high.

Ben Lomond Buckwheat (Eriogonum nudum var. decurrens)

Belonging to the same family as the spineflower, this variety of naked buckwheat is also rare and endemic to the Santa Cruz sandhills. Its leaves form dense basal rosettes and the tiny flowers sit atop long spindly stems.

Common Fiddleneck (Amsinckia menziesii)

These early bloomers with their charmingly twisted tops will pop-up in droves. As the plant grows, the stem uncoils, and new flowers emerge, while the old flowers develop into seed pods along the lower part of the stem.

Western Heart’s Ease (Viola ocellata)

Wilder Ranch has a handful of native violets, ranging in colors from white to yellow. These are often found in the transitional zones from meadow to chaparral to redwood forest.

Fairy Lantern (Calochortus albus)

Another stunner from the genus Calochortus, this species has a different stature than C. uniflorus and C. luteus. Rather than a bowl shape, this species has flowers that drop like little lanterns. Find it on the edges of grassland and woodland habitats.

Purple Owl’s Clover (Castilleja exserta)

This species belongs to the genus Castilleja, which includes Indian paintbrushes. Like other related plants in the family, this is a hemiparasite which derives some of its nutrients directly from the roots of other plants.

Fremont’s Deathcamas (Toxicoscordion fremontii)

This perennial plant grows back year after year from bulbs underground. It’s referred to as deathcamas because all parts of the plant contain a toxic alkaloid that some consider more potent than strychnine.
