Fireworks sundrops (Oenothera fruticosa ‘Fireworks’) explode with color in the Home Landscape Gardens during summer. Flowering best in full sun, drought-tolerant sundrops must have well-drained soil. This winter-hardy, summer-blooming perennial has exceptionally cheery, 3- to 4-inch flowers, and a loose, sprawling habit that softens edges of walkways and paths. Fireworks is selected for its dusky purple flushed leaves and red buds.
