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 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
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 longipetala
Restricted to swales and moist areas in coastal grasslands from San Francisco to Monterey, this uncommon native is well worth growing. Bluish-green evergreen blades form erect clumps one foot to 20 inches tall. Early spring brings beautiful lavender-blue flowers with dark purple venation. Full sun in coastal areas, a little shade inland with regular water through the bloom period. Can go dryer once flowering is finished. Deer resistant.
