Description
The Prairie Evening-primrose (Oenothera lindheimeri) is native to the North American prairies and produces a nearly weightless display of white and pink flowers from June until the first frost. Its slender, widely branched stems sway in the slightest breeze, earning it the nickname "butterfly magnet." Cultivars such as "Siskiyou Pink" offer more intense color, while the wild form blooms a delicate white to pale pink. It is especially striking as a bedding, container, or rock garden plant against dark backgrounds or when paired with grasses.
Care instructions
Plant in full sun in a warm location on well‑drained, somewhat sandy or loamy soil; avoid waterlogged conditions. Water only during extended dry spells, and apply deeply rather than frequently. Prune spent shoots in early spring (late March to early April) to encourage bushy regrowth; leave stems in place in autumn for winter protection. A mulch layer of leaf litter or pine needles over the root zone helps through winter. On heavy, compacted soils, add sand or gravel before planting to improve drainage.
