Mountain mahogany is one of those rare native shrubs which can easily be pruned for narrow garden beds. Grows on dry slopes in chaparral or at the edges of woodlands. Provide full sun to light shade. It is surprisingly adaptable to diferent water regimes, from moderate irrigation to no water once established. Somewhat deer resistant.
Cercocarpus betuloides var. blancheae
This rare and beautiful variety of our native mountain mahogany offers larger, birch-like leaves with fuzzy and whitish undersides. The highly useful from generally reaches 8 – 15 ft. tall, but only spreads to about 6 ft. wide, making it ideal for narrow locations where a screening, evergreen, fast-growing bush is needed. Small, disk-like, creamy flowers appear in the spring, followed in summer by seed pods with hairy, grey tails which curl upwards, giving the plant a silver halo. Over time, the trunks are covered in a smooth, grey bark. The Island mountain mahogany typically grows much more rapidly than our local variety and is tolerant of moist or dry soils once established and part shade to full sun. Heat isn’t an issue. A great candidate for a container, where it is very amenable to pruning.
Chamaecyparis lawsoniana ‘Nidiformis’
A very unusual and hard to find form of the native Port Orford cedar.

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.

Dicentra formosa
Ferny foliage makes a lacy groundcover in shady areas. Clusters of pendulous, pink, heart-shaped flowers in spring and into summer. Will spread rapidly when happy, enjoying moist but not soggy woodland conditions. Tolerates dry shade where it goes dormant with drought. Early nectar source for hummingbirds and bumble bees. Deer resistant.
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.
Dryopteris expansa
A very elegant native fern, with soft, bright green, finely divided fronds and a gently arching form. Rarely offered in California nurseries. Mature plants reach up to 3’ tall and wide, make them suitable for most garden spaces. Grows in moist, shady woodlands, mostly along our coast, from the Central Coast north to Alaska. Winter deciduous. Very similar to the lady fern, but with triangular-shaped fronds, not diamond-shaped. Said to be deer resistant.
Dryopteris filix-mas
The male fern is a beautiful, large, deciduous fern, native to much of Europe, Asia as well as North America, where it is uncommon in California. Large and slightly arching, the medium green fronds can reach 3 ft. tall and form a sizable clump. This fern increases slowly from stout rhizomes making it a fine choice for containers. An excellent addition to the woodland garden where it is easy to grow in part to full shade. Prefers humusy soil, rich in organic matter, though it is adaptable and accommodating. Best with regular to moderate watering. Rabbit and deer resistant.
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 californicus
California bottlebrush grass is a tall robust grass with broad, bright green blades and nodding brushlike flower spikes. Uncommon in the wild it can be found in coastal counties on shaded banks and wooded areas, including redwood forests. Displays 3 - 6 ft. tall flower stalks with low foliage up to 1 ft. high. Provide moderate to infrequent irrigation. Deer resistant.
