Nemophila menziesii – Frosty Blue
An interesting seed strain of the charming, ANNUAL baby blue eyes. Found in many habitat types throughout California, this beauty has long been in cultivation. The slender, succulent, lobed leaves grow 4 - 6 inches tall, spreading and spilling about 1 ft wide. The "Frosty" in the name refers to the silvery color to the foliage, which contrast nicely with the profusion of gorgeous, bright, baby-blue blossoms. Spectacular in drifts, where it can spill and cascade, at the front of a garden bed, in meadow plantings, rock gardens or in containers. Plant in full sun to light shade where it is early to bloom during the cool of spring. Hot weather triggers seed production. The large black seeds are relished by birds. Reseeds readily.
Oenothera elata ssp hookeri
Found in coastal areas from Sonoma County down to San Diego County. A vigorous, showy, winter-deciduous perennial that makes a dramatic border or background planting in full-sun gardens. In late summer into early fall, sprays of large, cheery, bright-yellow flowers with flat, papery petals top tall stalks up to 5’ high that are clothed with light-green lanceolate leaves. Blossoms provide a late season sweet treat for native butterflies and bees. As the name suggests, flowers fold and close during the heat of the day. May vigorously seed about. Moderate to occasional water once established.
Oxalis oregana
A natural companion of coast redwoods where it forms low carpets of clover-like foliage. Useful ground cover for the woodland garden where it competes well with tree roots and thrives in partial to deep shade. Low and spreading with spring flowers that can range from white through dark pink . Best with humus in the soil and some summer moisture, though it is drought tolerant in coastal zones. Deer resistant.
Oxalis oregana ‘American Beauty’
This remarkable selection of our native redwood sorrel has perhaps the largest flowers of any of the forms we've seen. The big pink blooms appear in spring above the lush, green, clover-like foliage.

Oxalis oregana ‘Klamath Ruby’
Low spreading groundcover which thrives in the shady conditions of Douglas fir and redwood forests. The cultivar ‘Klamath Ruby’ offers dark green clover-like foliage with beautiful burgundy backed leaves. White flowers with pale pink veining on the petals bloom in the spring. A lovely groundcover for a shady garden with some summer water, though it is drought tolerant in coastal zones, once established. Deer resistant.
Oxalis oregana ‘Smith River White’
This Cal Flora selection carries white flowers with thin pink lines on the petals held up above the foliage, thus creating an effect somewhat reminiscent of our small native anemones. The foliage is handsome with dark olive green tops and purple-red undersides to the leaves. The perfect ground cover for deep to moderate shade with some summer moisture. Drought tolerant when grown in more coastal areas. Rampant when its needs are met, it competes well with tree roots and is the perfect companion to other redwood forest understory plants. Deer resistant.

Penstemon speciosus
Found in higher elevation localities of inland Northern California, royal penstemon is a vibrantly colorful addition to the dry, full sun garden. In summer, the large, saturated blue-purple florets are held in clusters on stems rising almost 2’ tall above a low, evergreen rosette of glossy, strap-like foliage, reaching 1' - 2' wide. Attracts a multitude of pollinators. Does best with decent soil drainage, and inland sites that provide seasonality—colder winters, and hotter summers. Drought-tolerant once established.
Petasites frigidus var. palmatus
A bold, beautiful and AGGRESSIVE creekside native, found in coastal and montane regions in California, north to Alaska, where it grows along shady creek banks. The large, almost tropical, palmate leaves spread from thick creeping rootstocks to form large colonies. Flowers before the foliage fully emerges in the spring with flat topped clusters of white to pink flowers on 1-2 ft. tall stems. Requires shade and plenty of water and is useful as a soil stabilizer. To control its spreading nature, use in containers or in contained areas. It won't spread into areas which are dry. Dies back to the ground in the winter. Flowers attractive to a wide range of beneficial insects.
Petasites palmatus ‘Golden Palms’
Here is an exciting introduction of the western coltsfoot with wonderful golden foliage. Native to streamsides in low elevation forests, the broadly palmate leaves spread by creeping rhizomes. Careful thought should be given to its placement as it can be invasive. This bold foliage plant is great in containers or contained areas with regular water and part shade. Dies back to the ground in winter.

Best with light shade and some summer water, but will accept full sun in cooler areas. Keep bushy and in bounds with pruning.
Pinus contorta ssp. bolanderi
A close relative of the shore pine, the pygmy pine occurs in the coastal pygmy forests of Mendocino Co. This rare and threatened pine only reaches a height of about 6 ft in the acidic soils of its native habitat but acts more like the shore pine in a garden setting, reaching up to about 30 ft in time. The upward reaching stems are clad in short needles with small cones produced on the ends. Provide full sun near the coast and a little afternoon shade inland. Needs moderate to occasional irrigation and decent drainage. Good container plant. Deer resistant.
Pinus contorta ssp. contorta
On windswept coastal bluffs from Mendocino Co. northwards resides this dense, picturesque shore pine. While small in stature on the weathered cliffs of our shoreline often reaching only 6-10 ft. in height, in a garden setting the shore pine is a small to medium sized tree, growing to about 30 ft. Short, dark green needles cover the stems with small cones. An excellent compact conifer for the medium sized garden or in a container where it stays more diminutive. Provide full sun and occasional deep irrigation once established. Needs decent drainage. Deer resistant.
