Heuchera micrantha
This is our common alum root which is usually seen on shady cliffs and roadbanks adjacent to forests. Easy to grow in garden situations. Forms low mounds of foliage topped with dainty white flowers on long stems. Likes moisture, but tolerates considerable drought and takes deeper shade than most Heuchera species. This species attracts hummingbirds.
Heuchera micrantha ‘Martha Roderick’
Here’s a pink flowered form of the normally white flowered native alum root. Foliage forms handsome clumps topped with slender stalks 1 - 1 1/2 ft. tall of tiny pink flowers. Excellent in woodland setting for border, slope or rock garden. Drought tolerant but best with a little water. This species attracts hummingbirds.
Heuchera pilosissima
Native to the coast from Mendocino to Santa Barbara Counties, this perennial forms compact, evergreen clumps of light-green scalloped leaves. Stocky flower stems 12 – 16 inches long carry small white-pink flowers in early summer. Perfect in coastal areas where it can grow in sun to light shade and will be drought tolerant once established. Must have part shade and some summer water inland. Plant in mass for a nice ground cover in a woodland setting or in mixed plantings with shrubs and ferns. Attracts hummingbirds.
Heuchera rubescens
The pink alumroot stands out with bell-like flowers of pink and white held in clusters on slender stems up to 1 ft tall. The round, scalloped leaves form low, dense mats up to 1 1/2 ft wide and about 6 inches high. This western mountain dweller looks beautiful in a rock garden but will do well in any situation with part shade and good drainage. Needs moderate to occasional irrigation once established. Attracts hummingbirds. Great in a container.
Hierochloe (Anthoxanthum) occidentalis
Here is an interesting and elegant grass native to coniferous forests. Broad, bright green, sweetly scented blades grow a foot or more tall.

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 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 innominata
