Thick green flower buds hold bright yellow daisies summer through fall which are attractive to bees and butterflies. Best in full sun where it is drought tolerant once established. Tolerates heavy soils and is said to be deer resistant.
Grindelia hirsutula
Easy to grow, vigorous native perennial that is adaptable to a variety of soils and watering regimes. Grows 1 - 2 ft. tall with good-sized bright yellow daisies over a long period from spring into summer. An excellent nectar plant to add to a habitat garden. With a little grooming and dead heading this sometimes rough looking perennial can look quite handsome in a garden setting. Requires full sun and little to no summer water. Said to be deer resistant.
Hazardia squarrosa v. squarrosa
For a splash of color in late summer and fall, this goldenbush is a great choice, providing clusters of cheery, golden flowers at the height of the dry season, which supply food for butterflies. Birds enjoy the seeds which follow. Rounded leaves with sawtooth margins line the stems and emit a wonderfully sweet scent. This seed strain comes from a hot area in Big Sur and is remarkably compact and rounded, reaching about 3 ft. tall and wide. We’ve found it to be very adaptable, tolerant of clay soils and zero to occasional irrigation. Likes full sun but will accept a little shade. Plant with buckwheats, Salvias, and California fuchsias. Not usually available in Northern California nurseries.
Helianthella californica
Native perennial sunflower growing in chaparral and woodland communities throughout much of California. Forms clumps of dark green, lance shaped leaves under a foot tall.

Iris douglasiana – Robust Form
We discovered this incredibly striking form of the popular Douglas iris near Tannery Gulch, outside of Occidental. The dark, evergreen leaves reach up to an astounding three feet in height, and are exceptionally broad. Even though these are grown by seed, the flowers are a dependable lavender-blue, with sprays of white and yellow, held on tall stalks reaching up to a foot above the foliage! Grows well in dappled shade in hotter areas, but can take full sun where there is coastal influence. While drought tolerant, occasional deep soaks keep them looking verdant and vigorous. Deer and gopher resistant.
Iris douglasiana v. major
This rare form of the Douglas iris occurs throughout Marin County, offering a rainbow of possible flower colors, including blue-purple, mauve, creamy yellow and white, with all sorts of gradations in between. Since these are seed grown, the color will be a surprise when they bloom. The spring blossoms often have striking venation, and are held on stalks 1’ – 2’ high. Foliage clumps generally reach about a foot tall and spread to form extensive colonies of evergreen, strap like leaves. Plant in full sun in cooler areas, but provide some shade in hotter zones. Plants require little water once established, and are perhaps a little more drought and heat tolerant than the straight species. Deer and gopher resistant.
Iris fernaldii
Rarely offered in nurseries, the creamy-white to soft, buttery-yellow flowers of Iris fernaldii brighten up any dry shade to part-sun, inland garden in April. The flowers rise a foot above the evergreen, narrow, strap-like, deep-green foliage. This patch-forming Iris can be found in the more inland canyons of Northwestern California, from the Santa Cruz mountains, throughout inland Sonoma County, to Lake, Colusa, and Glenn counties. Fernald’s iris is well adapted to both extreme heat and cold, but can also perform well in full sun on the coast. Native bees and butterflies are attracted to the cheery flowers of this iris. This species prefers decent drainage and is drought tolerant and deer resistant once established.
Iris macrosiphon
A widespread and variable species growing throughout Northern California’s coast ranges and Sierra Nevada foothills. Our crop is grown from seed collected in western Sonoma County which has lovely lavender-blue blossoms April through May. Forms small clumps of narrow and slightly arching blades under 18 inches tall. Often found on wooded slopes, in openings or edges of forests where it will form small patches. Prefers good drainage, drought tolerant, or just a little summer moisture. Deer resistant.
Iris macrosiphon ‘Mount Madonna’
A charming little Iris discovered by Wintergreen Nursery on Mt. Madonna on our central coast. In spring, lavender flowers with deep purple veination and a splash of yellow sit atop dense, fan-like clusters of narrow, blue-green leaves. Reaches a height of about 10 inches and spreads slowly to form little clumps. Provide bright, filtered shade and low to no water once established. Will tolerate full sun in cooler areas. An excellent Iris for a rock garden which attracts bees and butterflies. Deer resistant.
Juniperus communis ‘Point Saint George’
A striking selection from our northern coast of a species that is widespread across the Northern Hemisphere but rare on the coast of California. Sadly, the original population no longer exists due to seaside erosion. Forming dense mats of silver-green foliage under six inches tall, it slowly spreads to several feet wide. A perfect addition to the rock garden, preferring decent drainage and occasional water once established. Also works well as a container plant where the branches can cascade over the sides creating silvery waterfalls. Likes full sun to light shade. Deer resistant.
Keckiella cordifolia
This Penstemon relative produces a profusion of bright red-orange, tubular flowers on the branch tips late spring into summer which are adored by hummingbirds. It likes to climb through tall chaparral shrubs or spill down slopes. Forms an open arching mound 3 ft. by 3 ft. but can climb 6 ft. or more. Deciduous with winter cold or summer drought, semi-evergreen in milder coastal regions. Requires good drainage in sun to part shade. Moderate to little summer water. Deer resistant.
Lathyrus vestitus
From woodland to chaparral throughout much of the California coast ranges comes this charming sweet pea relative. Clusters of dainty flowers ranging in color from white to pink and lavender grace this evergreen vine in the spring, followed by clusters of small peapods. Plant along a fence or amongst shrubs where it will climb up to 8 ft. tall and wide. Provide light shade inland but will tolerate full sun near the coast. Drought tolerant once established but will also accept occasional irrigation. This vine is a host plant to the silvery blue butterfly and the arrowhead blue butterfly.
