About Dense Ginger Lily

Hedychium densiflorum · also called dense ginger lily, bottlebrush ginger lily · tropical

Hedychium densiflorum is a clump-forming rhizomatous perennial native to the eastern Himalayas, notably the Sikkim region of India and Nepal, where it grows in moist montane forest margins. It produces exceptionally dense, bottlebrush-like spikes of small, fragrant orange or pale-orange flowers in mid- to late summer and is one of the hardier species in the genus. The most important care fact is that it needs a long, warm growing season to build up rhizome energy before the cold sets in — a sheltered south-facing border is ideal in temperate gardens. Hedychium species are considered mildly toxic to pets.

Preferred mix: Rich, moist, free-draining loam or amended garden soil

Watch for — Vine weevil grubs: Otiorhynchus sulcatus larvae feed on rhizomes in containers; use pathogenic nematodes (Steinernema kraussei) applied in late summer when soil temperature exceeds 5 °C, or treat with an approved compost drench.
