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.
OH MY DARLING, OH MY DARLING, OH MY DARLING Clementine you are lost ….Not lost at all this wonderful Verbascum is delightful and blooms repeatedly from spring to late summer. To 3′ tall or taller in ideal conditions, spires of soft orange to pale yellow depending on the temperature have a central bee of lavender feathers. Adorable and conspicuous as when observed as a cut flower of which this flower is great. The spires of flowers erupt directly from the center of a basal rosette of flat green leaves. Full sun, average to enriched soil that drains with light, consistent summer water. Remove spent blooms and another round will begin. Does not seed around. Mix with other sun-loving perennials with similar cultural requirements. Agastache, Digitalis lanata, Penstemon ‘Enor’ for a LONG LONG flowering spectacle. Winter dormant. Cold hardy and easy to grow. Great flower color for mixing or for tone on tone continuity- for that try it combined with Digitalis x ‘Honey Trumpet’.
Big ol magical biennial and we couldn’t imagine a garden without it. The first year it produces a large (2′ wide) rosette of huge furry white leaves. They lie flush with the ground. The following year total transformation occurs. A spike from the center of the rosette and soars to 6′ or taller. Its lined densely with furry white buds that pop open to reveal electric yellow soft looking flowers. The inflorescence will often wind this way and that. Even after bloom is through this tower remains spreading quantities of seed all over. Germinates best in open disturbed soil and they will germinate. Move them or thin them in spring. Snow white perennial with oodles of architecture. Full sun and rich, well drained soil. It makes due with less than perfect conditions but this way is the most impressive. Loved by pollinators. Light summer water if it looks like it needs it. Established plants get by with no water.
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.
Turkish speedwell is an excellent low water creeping ground cover that performs wonderfully in our climate. Flush with the ground this evergreen creeps in well drained average to enriched soil to several feet wide in several seasons. In April to May carpets of sky blue flowers obscure the entire plant. Very pretty. Roots as it grows, excellent for erosion control on a small scale on steep slopes. Regular summer water speeds growth but once established it takes summer drought very well. Full sun to the very lightest shade. Dies out in compacted soils- make sure to double dig the area around where it is to go to incorporate oxygen in the soil. For tired plantings simple overspread compost on top of it and let it settle between the leaves in early spring. Easy to grow hardy little ground cover. Moderate deer resistance.
Its been around for a long time and its an introduction that has stood the test of time. This low mounding evergreen perennial is beyond delightful when it alights in masses of deep blue flowers from late February to late April. Each simple blue flower has a small white eye but the effect from a distance is a pool of blue. To 8″ tall and forming large 2′ x 2′ wide patches in full sun in rich to average well drained soil. It excels on slopes and in rock gardens. The new growth that follows is tinted mahogany before become strong glossy green. Cut back by 1/3rd after blooming to create a much denser and ultimately more floriferous plant. Light, consistent summer water. Excellent bold backdrop to early and mid blooming bulbs. We suggest large white Crocus vernus followed by Narcissus ‘Blushing Lady’. Very easy to grow. Long lived for a speedwell.
Sturdy spire of a perennial with symmetry in mind. Whorls of pointed foliage lines the stems on the 5 tall plants. At the top vertical spikes of fine periwinkle blue flowers appear and grow. They remain pretty for weeks. In fall the still standing stems take on bright yellow fall tones and holds it for several weeks. Full sun and rich, well drained soil with regular summer irrigation Becomes more tolerant of drought with age and establishment. This form is popular for its occasional tendency to fasciate. A harmless contortion of the flower spikes. Cool cut flower.
The white flowered form of culvers root- but seldom called that in the PNW. Slender perennial with multiple vertical stems clad in symmetrically space pointed foliage surrounding the stem. At the tips in early summer multiple spires of pure white flowers give a really cool ethereal effect. Massed it is simply one of the coolest plants. Our form rises to just 4′ tall and forms slowly increasing clumps. In autumn the foliage that lines the stems often turns bright yellow and remains for a while- a second season of interest. Full sun to the very lightest shade in any soil of good fertility. Does well even in unamended clay as long as summer water is dependable. Long lived perennial that never requires division or fussing. Cool cut flower for big wild arrangements. Bees love it.
Unique and we think very pretty evergreen Viburnum. Small perfectly round leaves are placed in threes around the stems. In summer the terminal branches host clouds, or cymes I should say of tiny white flowers. They have no fragrance but are pretty to look at.. Moderately growing rounded shrub of great symmetry to 4′ x 6′ in 7 years. Full sun to part shade in rich, well drained soil with light but consistent summer moisture. Takes very dry conditions when established. At first glance this does not look like a Viburnum- which is charming. Its a very pretty dense growing first rate evergreen.
Rare but wonderful evergreen viburnum that has pretty elongated leaves held symmetrically on thick stems. The growth habit is branching in tiers. This displays the lovely foliage as well as the cones of white summer flowers at the branch tip. These turn into red and then black berries eagerly consumed by wildlife. To 9′ tall and 8′ wide in wide vase shape. Part shade in rich, well drained soil with regular summer irrigation. Takes very dry conditions when established. Extraordinarily cold hardy to below 0ºF with no ill effects. Moderately fast growing. SW China.
