Large lemon-yellow flowers appear atop 3-5 ft plants in the second year. Faithful to the moon, the fragrant flowers of these native plants open at night and attract night pollinators such as hummingbird moths, hawkmoths, and certain bees. The entire plant has been used in traditional herbal medicine. The tiny seeds can be pressed to make an oil that is used topically to hydrate skin. Plants are a biennial and produce a short rosette (cluster of leaves) the first year, followed by 3-4 ft. stalk with blooms the second year. Native to North America and fast growing, it is a good choice for the early stages of native plantings especially on dry soils. It establishes early, covering the soil during the first few years while slower native perennials get established. It has a biennial lifecycle so it will slowly disappear as other, more long-lived plants take hold. Evening primrose is a little wild and lanky looking and it produces copious seeds so it may become weedy in a formal garden. Seeds are Upper Midwest genotype.
