This hardy, versatile perennial forms dense, grass-like clumps of arching, deep green foliage, reaching a mature height of 12–15 inches. It thrives in USDA zones 5–10 and flourishes in a variety of well-drained soils, including sandy or clay types. 'Super Blue' prefers full sun to partial shade and tolerates heat and humidity, making it ideal for temperate to subtropical climates. In late summer, it produces striking, lavender-blue flower spikes that attract pollinators, followed by small black ornamental berries in the fall. This species is deer-resistant, requires minimal care, and can adapt to a variety of garden settings, serving well as a ground cover, border plant, or accent. It does not exhibit notable fall color change but prefers a tidy, mounding shape. Drought-tolerant once established, this easy-to-maintain plant is a reliable choice for perennial beds and landscapes.
