King’s spear is a rhizomatous perennial that is native to the eastern Mediterranean. It features a clump of narrow, linear, grassy, gray-green leaves to 12” tall from which rises in spring a conical, leafy flower stalk to 3-4’ that is topped by a dense cylindrical raceme (to 12-18” long) of fragrant, large-bracted, yellow flowers (to 1” across). Flowers give way to globose green seed pods that mature to an attractive brown. Other common names for this plant include Jacob’s rod and asphodel.
No significant insect or disease problems.
Best in groups or massed. Perennial borders, cottage gardens or wild gardens. Stems with dried flowers or fruits are valued for dried arrangements.
