Oenothera speciosa ‘Siskyou’

Showy Evening Primrose

USDA Zone: 5-9

Plant number: 1.400.020

An terrific selection of one of our North American native wildflowers. This is a vigorous, spreading plant that will form a low patch of small, spotted, olive-green leaves. Large satiny deep-pink flowers appear from early summer into the fall, seeming to rest right on top of the leaves. Excellent choice for hot, dry slopes, this is a little too aggressive for the rock garden or border: place carefully. Also nice in containers. Use as a groundcover to take advantage of its spreading nature. Drought tolerant, once established. Easily divided in spring.
