Phonetic Spelling:oh-no-THER-ah froo-tih-KOH-sah

Genus:Oenothera

Species:fruticosa

Family:Onagraceae

Sundrops is a perennial, upright, day-blooming plant belonging to the evening primrose family. It thrives across most of North Carolina, with the exception of the higher mountainous regions. While it can be quite eye-catching along roadsides and in meadows, its full potential is best realized when cultivated. This plant also inhabits dry forests, glades, and rocky outcrops.

Sundrops flourish in moderately fertile, dry, well-drained soil and prefer full sunlight, although they can tolerate some shade. Adequate winter drainage is crucial for their health. In optimal conditions, they can spread rapidly, though they are not overly invasive. The bright yellow flowers, while short-lived, bloom successively over an extended period. In southern regions, the rosettes maintain a purplish-green hue throughout the winter months.

This plant is ideal for hot, dry environments, making it suitable for wild gardens, rock gardens, erosion control on slopes, meadows, native plant areas, and cottage gardens. Notably, it was honored as the NC Wildflower of the Year in 1989. The variety microcarpa can be found in boggy areas, while var. unguilata is typically located in sandhills and moist savannas.

The recognition of this plant as the 1989 NC Wildflower of the Year was part of a program overseen by the North Carolina Botanical Garden, with financial backing from the Garden Club of North Carolina.

In terms of pests and diseases, Sundrops face no significant issues.
