Hedychium densiflorum (Dense Ginger Lily) is a clump-forming, rhizomatous perennial boasting a profusion of fragrant, orange or yellow flowers in dense, cylindrical spikes, up to 8 in. long (20 cm), in late summer and early fall.
Grow in humus-rich, fertile, moist but well-drained soil in full/ part sun. Choose a warm position sheltered from cold winds and give a deep winter mulch. In hard frosts lift the rhizomes and store somewhere dry until spring.An alternative is to grow it in a large container on a warm, sunny patio and to overwinter indoors or under glass.
