One of the prettiest species of the genus, Oenothera fruticosa (Sundrops) is an upright clump-forming biennial or perennial boasting showy clusters of large, saucer-shaped, bright yellow flowers, 2 in. across (5 cm), atop reddish, slender, hairy stems clad with lance-shaped green leaves. Blooming profusely from late spring to early summer, the flowers open during the day, hence the common name of sundrops, and give way to club-shaped seed capsules which persist into autumn. They rise from a reddish-purple rosette which is evergreen in mild winter areas. A valuable plant for its ability to grow in poor soils and tolerate drought. Provides a bold splash of color in the summer garden.

• Grows up to 2 ft. tall and wide (60 cm). This perennial wildflower spreads rapidly under favorable conditions but does not usually become aggressive.
• Best in full sun in average, dry to medium moisture, well-drained soils. Tolerates poor soils, drought and light shade.
• Great choice for prairies and meadows, wildflower gardens or naturalized areas. May be planted in beds and borders or as a groundcover.
• Keep an eye out for leaf spot, powdery mildews, downy mildews, root rot, slugs and aphids.
• Propagate by division in early spring, or by softwood cuttings of unflowered shoots from late spring to midsummer.
• Native to eastern North America.
