Evening Primrose


Evening Primrose Plant Features

The subtle pink, upward facing, cup-like flowers of evening primrose are so cheerful they almost seem to smile at you as you pass by. This easy-care sun worshipper is a snap to grow and tolerates a variety of tough conditions. Evening primrose grows about 2 feet tall, but has a tendency to sprawl in a casual manner. That's what makes evening primrose a great groundcover for exposed hillsides or slopes. The fragrant flowers appear all summer long and will entice butterflies and hummingbirds to your garden. Rabbits and deer generally do not feed on evening primrose. Hardy from zones 5-9.

Evening Primrose Growing Instructions

Evening primrose thrives in a sunny location that receives at least 6 to 8 hours of direct sun a day. The plants are not fussy about soil type and will grow and spread in even poor sandy soil. Evening primrose can become invasive so plant it where you can appreciate its spreading nature.
