Hypericum olympicum var. uniflorum (Single-flowered Olympic St. John's Wort) is a beautiful dwarf, woody-based perennial from the Balkan Peninsula, particularly southern Bulgaria and northeastern Greece. Forming a compact mound of small, attractive gray-green foliage, this diminutive selection produces large, brilliant golden-yellow flowers with a prominent cluster of golden stamens at the ends of its stems in midsummer.
The contrast between the bright flowers and silvery foliage makes this an especially attractive plant for the rock garden, where it provides a long season of interest. Naturally suited to rocky, well-drained habitats, it thrives in full sun and appreciates excellent drainage, particularly during winter dormancy. Drought tolerant once established and an excellent choice for alpine troughs, raised beds, and gravel gardens. Hardy to approximately USDA Zone 5.
