Sundrops 'Fireworks' (Oenothera f. 'Fireworks') is a compact perennial grown for vivid yellow, cup-shaped flowers and standout foliage tones. You will notice red buds and red-tinged stems set against bronzy-green leaves, creating color contrast even before bloom.
Plant it in full sun for the strongest flowering, and expect good performance in partial shade as well. Aim for well-drained soil and avoid winter-wet spots; consistent drainage helps it return reliably each year. Once established, it handles leaner soils well and fits easily into low-maintenance beds.
At a mature height of about 15-18 inches, this selection is easy to tuck along the front of borders, in rock-garden pockets, or in naturalistic plantings where you want bright, daytime color. The flowers arrive in succession, giving an extended show rather than a brief flush.
In the garden, you can pair it with grasses and other sun-loving perennials that complement its yellow blooms and warm-toned stems. Leave some seedheads to mature if you want to support wildlife; the flowers provide nectar and the seeds can be used by birds.
