About Slender Ginger Lily

Hedychium gracile · also called slender ginger lily, salmon ginger lily · tropical

Hedychium gracile is a slender, dwarf ginger lily from the lower Himalayan foothills of India, producing arching pseudostems topped in late summer with cylindrical spikes of small, star-like white flowers with a striking salmon-pink to orange-red stigma that become intensely fragrant at dusk. Its compact habit makes it an ideal choice for small gardens, patios, or containers in temperate climates. It is smaller than most Hedychium species, so good drainage is especially critical to prevent rhizome rot. The ASPCA lists closely related Hedychium species as non-toxic; slender ginger lily is considered non-toxic to cats and dogs.

Preferred mix: Humus-rich, well-drained loam or loam-based compost

Watch for — Rhizome rot in winter: The slender rhizomes are more vulnerable to cold, wet soil than larger-rooted Hedychium; lift container plants under glass before the first frost, or apply a 15 cm mulch and reduce watering sharply in October.
