Carex obnupta
From moist coastal sites to shady redwood forests comes this tall sedge, one of the tallest of our native sedges. Spreads vigorously to form dense drifts up to 4 feet in height. One of the more shade tolerant sedges, the slough sedge can grow under the darkness of a redwood canopy but will also accept full sun as long as it has access to moisture. A great plant for naturalizing in moist areas. Used by native peoples for basket making.
Carex pansa
A durable spreading sedge which can be used as a lawn substitute or unmowed meadow. Growing 8 -12 inches tall and spreading by rhizomes to form dense colonies of curling dark green foliage. The foliage is evergreen in mild climates and grows well in full sun to partial shade with regular to occasional water. Too much drought causes summer dormancy. Flowers appear in early spring but are not real showy. Deer resistant.
Carex praegracilis
Similar to Carex pansa but growing taller. The fine textured grass-like blades can reach a foot or more tall and spreads freely by rhizomes to form a thick weed smothering groundcover. Useful for meadows, green roofs, bio-swales, erosion control and as a lawn substitute. Can be left natural where it has a lush tousled appearance or trimmed occasionally for a low turf-like appearance. Tolerates drought, inundation, poor soils, salt spray, heat, cold, shade and foot traffic. Plant in sun to light shade where it requires some summer moisture but far less than a conventional lawn. Will go summer dormant if allowed to get too dry. Deer resistant.
Carex praegracilis ‘Chisai’
An excellent cultivar of the native field sedge, selected for it's compact form and slower spreading habit. Increases by short rhizomes to form a sturdy, dark-green carpet, 6 -8 inches tall and 1 - 2 ft wide. Grows more clumping and significantly tighter than the rapidly spreading forms more typical of the species. Still, it will form a solid, small scale ground cover or turf substitute, between stepping stones or mixed with bulbs and perennials for a meadow affect. Plant in full sun to light shade with occasional to moderate water. Tolerates light foot traffic. Deer resistant.
Carex serratodens
From serpentine meadows comes this lush, blue-green sedge. Our form grows 1 - 2 ft. tall and spreads at a moderate pace, creating broad drifts over time. Needs moderate to regular moisture and full sun to part shade. Often goes semi-dormant in winter at which time the plants can be cut back to just a few inches. A useful sedge for gardens on serpentine or for bank stabilization where it can provide cover for tree frogs and other critters. Does not require serpentine soils to thrive. Deer resistant.
Carex spissa
Native to watercourses in coastal sage scrub, chaparral and oak woodlands from San Luis Obispo County to San Diego County. Has proven adaptable and easy to grow here. Wide silvery blades 3 - 4 ft. tall with brown nodding flowers. Sun to light shade. Regular to moderate water. Deer resistant.
Carex tumulicola
This is the TRUE Carex tumulicola, the foothill sedge, not to be confused with the so called Berkeley sedge which is correctly identified as Carex divulsa and is non-native AND invasive. Foothill sedge has a wide distribution in California and north to Washington. A tough and adaptable tufted evergreen growing 12 inches (or more) tall and spreading slowly by underground rootstocks. Useful as an informal groundcover under shrubs or trees, for a meadow planting or for soil stabilization where the spreading roots help control erosion. Best with some shade unless right along the coast. Responds to water but is able to tolerate periods of dryness.
Chlorogalum angustifolium
You may be familiar with the common soap plant and its tall stalks of delicate white flowers. But this unusual, diminutive species of soap root is much smaller, only reaching 1 – 2 ft. high. Rarely offered in nurseries, this species has short, narrow leaves which are not wavy like the common soap plant. Grows in dry grassland and open woodlands in the northern Sierra foothills and coast range. Enjoys full sun to light shade and no additional irrigation once established. Tolerates clay. The seed for these plants came from Windsor and was generously given to us by Vicki Wilson.
Chlorogalum pomeridianum v. pomeridianum
Known for their large, fibrous bulbs historically used by indigenous peoples and early settlers for soap, food and to stupefy fish. Long, wavy-margined leaves form a rosette in winter followed in late spring by tall, airy flower stems bearing small white flowers that open in the late afternoon and evening. Great in naturalistic settings in full sun to light shade. Needs to go summer dry once established. Larval food source for the Western Brown Elfin butterfly.
Clarkia amoena ssp. whitneyi
Nearly extinct in the wild, this beautiful ANNUAL was found in coastal communities in Mendocino and Humboldt Counties. Growing 3 ft. tall and wide, the branched leafy stems are topped with a long succession of 3 inch cup- shaped flowers. The large flowers are light lavender-pink with whitish areas at the base of the petals. Clarkias make excellent garden plants needing very little and giving much in return. Plant in full sun to light shade, as a filler among trees or shrubs, in mixed flower border or meadow planting. A little water while flowering will extend their show. Good container subject too. Excellent cut flowers. Seems to be deer resistant. Attractive to bees and butterflies.
Clarkia rubicunda
Showy and floriferous, with gorgeous, cup shaped blossoms of silky, pink-purple petals featuring a dark red center with a long bloom from late spring into summer. This endemic, ANNUAL wildflower grows in openings of woodlands and chaparral near the coast, mostly in the central part of state. Grows 2-ft. tall or more in full sun with low water needs. Tolerant of heavy soils, the exuberant blossoms attract bees, butterflies and moths, including Sphinx moth species. Performs well in containers and is an excellent cut flower too. Deer resistant.
Clarkia williamsonii
The incredibly showy flowers of this native ANNUAL will take your breath away in late spring and early summer. The large, lavender-pink, papery flowers feature deep, burgundy-red brush strokes and cheery white centers. Plants form a loose mound about 1 ½ ft. around. Butterflies and other pollinators love Clarkias. Native to the Sierra foothills, where it grows in full sun to light shade. Plants enjoy moisture while they are developing in the winter and spring, but are accustom to hot and dry summers. Needs decent drainage. Reseeds readily, as long as there is exposed soil nearby. Deer resistant!
Collinsia heterophylla – Sierra Form
A striking form of a native annual wildflower found in open woodlands in much of California. The open lipped flowers are stacked in tiers, and said to look pagoda-like. In this Sierra form from Tuolumne County, the upper and lower lips are dark purple with a light central patch with scarlet nectar guides. This charming woodlander is best in bright shade, in edges and openings, or under oaks, where it blooms from mid spring to early summer. Grows around 2 ft. by 2 ft. When happy it will reseed and those seedlings will require no irrigation. A bee and butterfly favorite.
Cucurbita foetidissima
Found in valley grasslands and coastal scrub environments of Central and Southern California, the buffalo gourd is a deciduous perennial ground cover or vine that is sure to grab attention. In late winter and early spring, this vigorously spreading gourd emerges from a tuberous root, potentially spreading to 20’ feet or more, producing big, triangular, gray-green fuzzy leaves, followed by large, showy, orange-yellow, bell-shaped flowers in summer which attract bees. The round fruits, about 4 inches across, are green-striped when young, maturing to yellow. As the fruit matures, it is too bitter for humans to eat. The mature fruit is used by native peoples for decorative purposes or for making musical rattles. Plant in full sun. Drought-tolerant once established.
Danthonia californica
California oatgrass is a native bunchgrass found throughout mountains and coast ranges in both open and partly shaded areas. Forms dense leafy tufts with flower stalks of nodding spikelets to 1 1/2 ft. tall. Not to be confused with the invasive alien wild oats, this native makes a good basic grass for a meadow planting. Withstands trampling and traffic. Good for soil stabilization. Sun to very light shade. Little to no summer water once established. Deer resistant.
Delphinium trolliifolium
Towers of dense, blue purple flowers reaching up to 4 ft high make this one of our most striking native larkspur. The robust stalks rise above elegantly cut leaves featuring an appealing matte finish. The new leaves emerge in winter after a summer/fall dormancy, followed by the stunning floral display in early spring. Native to the northwest corner of our state, where it grows in oak woodlands, bright, coniferous forests and coast chaparral. Enjoys moisture in the winter and spring, but should be allowed to go somewhat dry in the summer when dormant. Provide light shade away from the coast. Attractive to butterflies and hummingbirds. All parts are poisonous if ingested.
Deschampsia cespitosa ssp. cespitosa
Tufted hairgrass has a large natural distribution, in both the northern and southern hemispheres, in high elevation mountains as well as lower elevations along the coast. The seed for this crop is from coastal Sonoma County, a good choice for low elevation gardens. Forms a deep-green bunch of finely textured blades up to one foot tall with airy flower panicles extending two foot or more above the foilage. Useful framework among wildflowers or with perennials and shrubs. Sun to light shade and a little summer water. Deer resistant.
Deschampsia cespitosa ssp. holciformis
This native bunchgrass makes its home on windswept coastal bluffs from Central CA north to British Columbia. The tidy, evergreen clumps of foliage reach 6 – 12 inches tall and get at least as wide. Stiff, green leaf blades can give plants a spiky appearance, but also make this variety look more symmetrical than many native grasses. The narrow Inflorescences can reach up to 2 ft tall. Does best with full sun near the coast, but enjoys some afternoon shade in hotter areas, where moderate irrigation is recommended. Grows well with iris, seaside daisies and other coastal species. Deer resistant.
Deschampsia cespitosa ssp. holciformis – Jughandle
This form of tufted hairgrass from the Mendocino Coast has a different look than those farther south. The bright green blades are relatively broad and stiff. The flower stalks are 1 1/2 to 2 ft. tall with panicles which emerge greenish then turn golden. A natural for along the coast, a little shade and moisture inland. Deer resistant.
Deschampsia elongata
Graceful fine-textured perennial bunch grass, native to partly shaded, seasonally moist areas in California. Features bright green blades and gently arching flower stalks 12-18 inches tall. Yellowish-green in spring, turns soft gold in summer. Deer resistant.
Dichelostemma congestum
A perennial wildflower with rounded, purple flower clusters held atop slender, naked stems. In late spring and early summer, the cheerful floral umbels rise 2 to 3 feet above low, grass-like leaves. Native to hillside grasslands and mountain meadows throughout western North America, this wild hyacinth species is taller than its Brodiaea relatives, with larger inflorescences than the similar blue dick. Usually spreads slowly by corms and seed to form colonies. An excellent nectar plant for the dry borders of pollinator gardens, alongside other native bulbs, and in meadow plantings. Plant in full sun to light shade with decent drainage. Water minimally and leave dry during summer dormancy.
Dichelostemma ida-maia
Blooming firecracker flowers are a sight to behold. Native to grassy slopes and woodland edges from Mendocino County to Southern Oregon, this distinctive native bulb is truly unique. Long, strap-shaped leaves give rise to tall, naked stems, 20 - 25 inches in height. Generous clusters of pendulous, one inch floral tubes of striking crimson with reflexed green tips reveal protruding little fringes of white. Bloom in late spring to early summer. Prefers lightly shaded areas that will go dry in summer after flowering. Does well in containers, as long as it is allowed to go dry once dormant. Flowers are custom built for hummingbirds and butterflies.
Dichelostemma ida-maia x multiflorum ‘Pink Diamond’
A natural occurring hybrid involving the red firecracker flower and a blue flowering species, producing bright, magenta-pink tubular flowers with charming reflexed tips like it's firecracker parent. Strap shaped leaves emerge in the spring with leafless flower stems following, 8-20 inches tall. The umbels of deep pink flowers are favored by hummingbirds and butterflies. Tolerant of different soil types in full sun to light shade. Dry conditions once it goes dormant is a must. Good container plant.
Dichondra donelliana
Dichondra is a small genus of flowering plants in the morning glory family that form a thick, mat-like ground cover of rounded leaves, once popular as lawn substitutes. This native species is uncommon in the nursery trade and in gardens, but has potential worth exploring. Native to California coastal plant communities on open slopes and moist grasslands, it forms a flat, perennial ground cover with tidy, rounded leaves, densely packed along creeping stems. The flowers are tiny and greenish-white, not real showy but interesting. An obvious application would be a small scale ground cover or meadow planting in areas with some moisture. Could be a candidate for green roofs or walls, where a low and spreading plant is the ticket. Plant in full sun on the immediate coast, otherwise light shade is necessary. Moderate summer water.
Elymus (Leymus) condensatus ‘Canyon Prince’
A beautiful selection from the Channel Islands off Southern California. Distinctive for the lovely, broad, silver-blue blades 2 1/2 to 3 ft. tall with wand-like grass flowers reaching up to 2 feet above the foliage. Accepts sun to very light shade and moderate to little water. Tolerates heavy soil. Spreads by rhizomes to form striking silver drifts, but is vigorous and aggressive. Best to use where a large patch is desired or where it is contained, such as a parkway strip. Cut back in winter to rejuvenate and remove old leaves. Drought and deer resistant.
Elymus (Leymus) triticoides
Spreading, turf forming, perennial grass found in somewhat moist areas in many plant communities throughout California. An important restoration species, useful for holding soil and enhancing wildlife habitat value. Growing 2-4 ft. tall and spreading widely with an extensive network of rhizomatous roots which both hold soil and help prevent exotic weed establishment within their dense mats of roots and foliage. Slender blue-green blades are topped with narrow flower spikes 4-6 inches long. Excellent for seasonally moist bottom land and riparian areas where it can grow in full sun to light shade and tolerates many soil types. Will tolerate some drought in heavier soils. May spread too vigorously for small gardens.
Elymus (Leymus) triticoides x ‘Lagunita’
Discovered by grass expert and John Greenlee, who describes it as his personal favorite ground cover grass for meadow installations. Often this species has blue-grey blades and grows tall and floppy, but 'Lagunitas' grows just 10 - 16 inches tall, with rich green blades. This form rarely flowers and is quite adaptable to soil types and watering regimes. The ability to tolerate both wet and dry conditions makes it valuable for areas that seasonally flood like rain gardens. A vigorous spreader, especially when well watered, but is better behaved in dryer sites. Once established, can be maintained with one or two waterings a month, keeping it green and fire safe. Tolerates trimming to about 4 inches, possibly more. Grows in full sun to light shade. Host plant to the Woodland Skipper butterfly.
Elymus elymoides
A species of wild rye, this tough, native, widespread, perennial grass, sports distinctive seed heads with a bottlebrush or squirrel tail appearance. Super adaptable and willing to withstand a wide range of soil types and depths. Even tolerates serpentine soils. Able to make a living in full sun where it is extremely drought tolerant. Grows one foot to 18 inches tall with shimmering, purple-toned flower spikes that age to beige, bristly, seed heads. A dependable re-seeder, perfect for sunny, low water using landscapes and erosion control. Host plant for a number of butterfly and moth species including the woodland skipper. Deer resistant.
Elymus glaucus
A stiffly upright, clump-forming grass with blue-green blades, native to much of the western U. S.. The flowers form bristle-tipped, narrow, vertical spikes, rising 2-4 feet tall. Easy to grow and a strong reseeder for full sun to light shade. Summer water keeps plants green longer, but will go dormant with drought. This very adaptable grass is excellent for bank stabilization in challenging soils. Deer resistant.
