Plants are covered by clusters of 2-3" wide, widely flaring, 4-petalled, glowing sunny yellow flowers in late spring and early summer and are held against red tinged foliage and even darker red new growth, flower buds, and winter rosettes. Fireworks Sundrops, a selection of our native Oenothera fruticosa subsp. glauca, but has a more compact, 12-18" high habit than the species. This is a tough and easy clump forming to short-rhizomatous, herbaceous perennial well suited to sunny, well-drained sites and plants typically need little additional attention once established in the landscape. Unlike many of the Evening Primroses, Sundrop flowers are open during the day providing nectar and pollen to a variety of bees, butterflies, and hummingbirds.
