In June and continuously until frost spikes emerge, to 2′ and hold clumps of luminous, soft lavender flowers. Each spike is in bloom for a week or more. New flowers are continuously produced. Remove spent spikes to tidy. Full sun and WELL DRAINED rich soil with regular summer water. Very drought adapted when established. In cold gardens its best on hot slopes. Freezes to the ground in winter, returns quickly in mid spring. Foliage is intensely aromatic of garlic when disturbed. Useful, pretty, long blooming. Moderate deer resistance.

Vancouveria hexandra

Inside-Out-Flower is a commonly seen terrestrial component in dry to moderately moist woodlands in our region. The duck foot shaped leaves are conspicuous and pretty and in late spring to mid-summer a continuous supply of dainty downward pointing white flowers. Spreads in gardens very well in enriched soil with regular summer water where it will quickly assume the role of an intertwining ground cover. Winter deciduous- un-like its close and much more drought adapted relative Vancouveria chrysantha (Yellow inside-out-flower, Siskiyou Vancouveria). This perennial is perfect for life among shrubs or mixing with other woodland perennials in part shade to shade. Adapts well to garden culture and thrives on regular summer irrigation. Locally native in the city of Portland. To 10″ tall and spreading. Some deer resistance.  Oregon native plant.

Verbena rigida

Vigorous and floriferous perennial Verbena for tough areas. Spreading by underground stolons in rich to average well drained soil this deep purple flowering perennial covers ground in short order. Full sun and light summer water when established to lengthen bloom time. Even then it begins flowering in June and continue unabated for two months. To 2′ tall and 4′ wide. Give it room to spread and do not pair with delicate neighbors. Hellstrips, Insanely hot and dry south facing hillsides. Freezes to the ground in winter- returns from the ground when truly warm weather arrives. Moderately deer resistant.

Vitex agnus-castus ‘Sensational’

Excellent California selection of Chaste tree with thicker, bluer flowers. Large growing shrub with aromatic finely divided leaves in mid-July in PDX spires of blue flowers erupt from each branch tip. It remains in bloom for 3-4 weeks. And if you remove spent flowers more will appear. Full sun and poor to average well drained soil. No summer water when established. Attains tree-like status with great age. May be pruned back hard in spring to contain the ultimate size. Blooms on new wood. Long lived and hardy below 0ºF. Leaves appear late in spring- often not until mid-May. Be patient. Loved by pollinators and bumble bees specifically. A shrub in full bloom will be a haze of drunken bumbles who after a day of working will often fall asleep in the flowers of this shrub. Tolerates the hottest sites and is very long lived.

Watsonia latifolia

A true red flowered Watsonia and one of the hardiest of the genus. Wide green spikey leaves rise to 2′ tall in spring. In late spring to early summer 3′ tall spikes of tubular true red flowers line the stems. Loved by hummingbirds and cut flower aficionados alike. Rich soil in full sun in a protected position- a south or west facing wall is ideal. Freezes to the ground below 20ºF- re-sprouts in spring. Forms an expanding clump to several feet across. A fun genus to experiment with in our climate. Rated as zone 7 in its native high elevation South Africa.  We think its more like 10ºF in our climate. Plant with royal red Lobelia tupa and Rosa ‘Bengal Fire’ for a red extravaganza. Excellent performance at the Oregon Coast. Somewhat deer resistant.

Watsonia x pillansii ‘Coral and Hardy’

We love Watsonias but the most successful climate is truly on the coast. This form is seed from a persistently hardy, well blooming plant that has survived in Portland. The majority of these seedlings will be coral/ orange/ light pink. To 20″ tall forming clumps in RICH, well composted soil in full sun. Regular summer water increases both the growth rate and the cold hardiness. Larger more established clumps are hardier to cold. Amazing cut flower that will produce several dozen spikes off of one good clump. Mostly evergreen. Foliage looks burnt below 20ºF and can freeze to the ground. This winter growing bulb is also immensely drought tolerant with a period of summer drought inducing dormancy. Place in a warm, protected location Near a south facing wall or fence. Mulch for the first few winters with dry leaves. Place in a location where summer dormancy is not an issue. Very fun to grow South African bulb. Excellent performance at the Oregon Coast. Not bothered by deer or elk- well the elk might step on them but they won’t eat them. Fantastic cut flower and clumps become huge there.

Whipplea modesta

Yerba de Selva or whipple vine, a wonderful small scale evergreen native ground cover. Related to Hydrangeas but this trailer is actually very droughtadapted.e In late spring clouds of small white flowers have  the same perfume. Scrambling plant to about 8″ tall and 2′ wide. Full sun to considerable shade. From Portland south this is a common understory component of the herb field. It grew happily in our back 40 where I grew up. There it made pretty scrambling patches between Vancouveria, snow berry and hairy honeysuckle. Often you would see our native columbine ( Aquilegia formosa) as an associate. Its very drought adapted when established but it improves with a few soaks over summer- never perpetually wet and never hot and wet. Otherwise an easy native that should be grown a lot more. Just the fragrance of the foliage endears it to me. For use as a small scale ground cover plant on 10″ centers. It will also gracefully trail over rockeries and walls. Butterflies adore the flowers. Competes well with invasives. Some deer resistance. It may be cut back in early spring to refresh. Once native in the Portland city limits. This is a great native understory for Arctostaphylos, which is frequently seen in the wild.    Oregon native plant.

Woodwardia fimbriata

Our native Giant Chain Fern that occupies specific spots in seeps randomly from CA to BC. Large pendant and trailing 3′ long glossy fronds form huge rosettes. Usually occupying permanently wet seeps on shady hillsides in cool places. The entire plant may be up to 5′ across. Evergreen but it benefits greatly from some early spring tidying of spent and aging old leaves. Part shade to shade in rich well drained soil with regular consistent moisture for the best look. Highly deer resistant. We’re honored to grow this, one of our most spectacular native ferns. Oregon native plant.

Woodwardia unigemmata

Relatively new fern with a great future ahead. Large growing evergreen chain fern from Asia with new growth lavishly dyed red- it settles to soft green with time. To 3′ across the fronds are held atop relatively long stems. The rubbery green leaves are finely divided with surprisingly soft lobes. Rich, moisture retentive soil in bright shade to shade. Spectacular plant at all times we have observed it. So far it has not suffered damage in my garden below 10ºF and appearance following a rough winter was good. Highly deer resistant. Spectacular.
