Iris douglasiana
Native to the California coast from Santa Barbara to Oregon. Grows both on the edge of coastal forests and on bluffs and prairies along the ocean. Clumps of evergreen, sword-shaped leaves increase readily and are topped with violet-purple blossoms early to mid spring. Important nectar producer for native bees. An adaptable garden subject for cool full sun to light shade. Drought tolerant once established, but occasional summer water will help keep foliage fresher. Deer resistant.
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 ‘Canyon Snow’
A dependable and floriferous selection of the native Douglas iris, with springtime flowers that are pure white with yellow markings on the falls. Broad shiny blades are mostly evergreen and grow a foot or more tall and form compact clumps. Plant in sun to part shade, particularly in hot inland areas, with moderate to little summer water. Prefers good drainage but will grow well on clay soils provided they are mounded up. Too much summer water on heavy soils will prove fatal. Deer resistant.
Iris douglasiana ‘Pt. Reyes’
This is the classic iris seen along our coastline. A vigorous form with compact dark green leaves and a profusion of dark purple flowers, spreading to form large clumps. Beautiful when grown in a meadow of native grasses and coastal wildflowers. Prefers light shade in warmer areas and occasional water for it to look its best. Pruning the leaves down to the ground in the Fall can help the plant maintain a fresh appearance. Deer tolerant.
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 innominata
A choice iris with slender, glossy, dark-green leaves and dainty flowers in late spring. Flower color can be from brilliant yellows to shades of purple. Native to the Siskiyou Mountains in Del Norte County, California, into southern Oregon where it forms low, dense, evergreen clumps in openings of woodlands or coniferous forests. This species does better in hot, inland areas than the Douglas iris. Requires good drainage and some summer water. This Del Norte County iris has been used in hybridization programs to produce the popular Pacific Coast Hybrid Iris. 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.

An excellent Iris for a rock garden which attracts bees and butterflies. Deer resistant.

A native iris hybrid thought to be a cross with Iris douglasiana. Flowers are a deep lavender in color, with purple-veined petals and yellow throats. Evergreen foliage is 12-18 inches tall and spreads to form 2-3 foot-wide clumps. Tolerates full sun on the coast but does best with afternoon shade inland. Occasional water keeps it looking good in summer. Like other Pacific Coast iris hybrids, it can be planted in the understory of oaks, where it will require little irrigation once established.

The evergreen foliage grows about 1 - 2 feet tall and spreads by rhizomes to form clumps up to 3 feet wide. Tolerates full sun on the coast but does best with afternoon shade inland. Occasional water keeps it looking nice in summer. A good plant for the understory of oaks, where it will require little irrigation once established. Drought tolerant and deer resistant.
Iris Pacific Coast hybrid ‘Purple & White’
A Pacific Coast hybrid iris with thick purple veins and a splash of yellow at the center of white flowers.

Features exceptionally blue foliage and and a vigorous spreading habit. This selection is shorter than the typical grey rush only reaching about 18 inches tall. An adaptable species, will thrive in moist soils, even shallow water but once established tolerates dry conditions too. Grows in sun to moderate shade. An excellent accent plant with its stiff, vertical foliage. 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.

Best in sunny locations with well drained soil and moderate to a little summer water. Tolerates light shade, does NOT like heavy, wet soils or deep shade. Deer resistant.
Lasthenia californica ssp. macrantha
Native along the immediate coast of California and just into Oregon, where it forms low, tight mounds of deep green succulent foliage. Cheerful, bright yellow daisies bloom over a long period. Best in full sun with some summer water and good drainage. Long blooming, open faced flowers are excellent sources of nectar and pollen for butterflies, bees and other pollinators.
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.

Lavatera (Malva) assurgentiflora
Light green, maple-like leaves with showy, rose-pink flowers with dark veination bloom over a long period from spring to fall. Native to the Channel Islands, this fast growing shrub will grow 10 ft. tall or more.

Pruning helps maintain a nice habit. Probably best in naturalistic garden designs. A favorite nectar source of orioles.
Layia chrysanthemoides
Light up your plantings or containers with this cheerful, ANNUAL wildflower. Boasting clear, bright yellow daisies with pure white-tipped petals, providing a spectacular springtime display. Similar to the common tidy tips, this species is a little smaller, though the flower heads are equally large.
