This spectacular native wildflower is everblooming with a profusion of large, bright yellow, four-petaled flowers. The narrow gray-green foliage gives the plant a lacy look in the garden. Calylophus thrives in the heat, and grows well in a wide range of soils, as long as they’re well drained. This tough plant is the star of any dryland rock garden or xeriscape.

Seafoam Artemisia, Artemisia versicolor

by 505 Outside | Aug 2, 2018 | Flowering Plants

Sun or Shade

Low Water

Mature Size: 8”X 18”

The fine-textured swirling silver green foliage of Seafoam Artemisia suggests cool water running through a dry desert garden. Although it has no showy blossoms of its own, it mixes well with Salvias, Penstemons and other brightly colored flowers and with ornamental grasses such as Little Bluestem for a subtle blend of textures. Seafoam Artemisia holds up well in winter and needs less trimming than its sprawling cousin, Powis Castle Artemisia.

Golden Columbine, Aquilegia chrysantha

by 505 Outside | Aug 2, 2018 | Flowering Plants

Full Shade

Medium Water

Mature Size: 2’X 2’ Blooming Season: Spring Flower Color: Yellow

Golden Columbine is the most heat tolerant of any high mountain Columbines allowing it to bloom longer in the season. Even after the last flowers fade, its lacy blue-green leaves are pleasant company for summer flowers. In a shaded runoff basin, Golden Columbine will self-sow, making a casual ground-cover.

Thrift, Armeria maritima

by 505 Outside | Aug 2, 2018 | Flowering Plants

Full Sun

Medium Water

Mature Size: 12”X 12”
Blooming Season: Late Spring
Flower Color: Pink

This plant is a rock garden favorite with its tidy mound of grassy foliage and profusion of rose-pink spherical flowers. Kept “deadheaded,” flowering will continue throughout much of the summer. Well drained sandy or loamy soil is best for Armeria maritima. It appreciates regular watering during the heat of summer, although drier conditions are fine for cooler times of the year. Armeria is perfect for interplanting with blue flowering Veronica and white Greek Yarrow, among others, for outstanding rock garden color combinations.
