Nursery contributed plant descriptions

A great perennial for the Bay Area & temperate climates! Gazillions of 1”, lavender, cup-shaped blooms with pointed petals are held atop masses of upright, wiry, 12” stems, waving gracefully with the breeze all Summer. Easy & fast growing, the slim, bluish-green foliage makes a dense mat, 2’-3’ across. Wahlenbergia krebsii puts on its best show when planted in rich, composty soil & full sun exposure. After bloom, cut back to 2” tall & top dress with compost sometime before mid-Spring for your next season of “WOW!” Lovely with roses, trailing over a rock wall or as edging.
