Oenothera berlanderi 'Siskiyou'
Common Name: Evening primrose
An extremely long blooming, easy care plant. A vigorous, stoloniferous grower that can be a bit of a thug, especially in sandier soils. It is less invasive and shorter than O. speciosa, but still a fast running plant that can quickly spread. Great numbers of 1-1/2", upright, clear light pink flowers are translucent in the sun. Blooms May through July and with periodic rebloom until October.
Height: 10-12 Inches
Spread: 12-18 Inches
USDA Hardiness Zone: 5-9
