Powellii, commonly called swamp lily or Cape lily, is a hybrid of garden origin resulting from a cross between two South African crinums, namely, C. bulbispermum (orange river lily) and C. moorei (natal lily). This hybrid typically produces a clump of narrow, strap-shaped green leaves to 3-4’ long and to 2-3” wide near the base from which rises a naked flower scape to 4-5’ tall which is topped with umbels of 8-10 showy, fragrant, trumpet-shaped, pink flowers (each to 4” diameter) which bloom in succession from late summer to early autumn.
