Agapanthus White Superior forms a tidy evergreen clump of narrow, strap-like green leaves. Strong green scapes rise above the foliage in summer and carry rounded umbels of large white tubular flowers with a subtle pale-blue sheen.
The cultivar brings clean vertical structure to borders and containers, and the flower stems are useful for cutting. It performs best with sun, free drainage, and moisture during active growth. Established plants tolerate some drought, while cold-climate gardeners can grow it seasonally in containers and move it under cover for winter.
