Hardiness: winter hardy to USDA zones 11-12. Care: best grown in moist, fertile, organically rich, well-drained soil in part shade, tolerates close to full sun. Size: grows to 6ft tall in a clump of stalks, leaves 12-15in long by 2-3in wide. Pests/diseases: fungal leaf spot and root rot may occur; spider mites may appear in dry weather. Used as tier-1 substitute for RHS, whose Alpinia galanga page carries no cultivation content at all.

Habitat: forests, scrub and grasslands, 100-1300m elevation, China/Indo-China/India/Malaysia. Climate: minimum temperature 15°C, optimal 27-32°C, tolerates 20-36°C; prefers 2,500-3,000mm annual rainfall, tolerates 2,000-3,700mm; high humidity preferred. Soil: pH 5.5-6.5 (tolerates 5-6.8), well-drained humus-rich soil; partial shade preferred but succeeds in full sun; tolerates some drought. Size: robust perennial, large clumps 2-3.5m tall, subterranean creeping copiously-branched rhizome, light red or pale yellow rhizomes 2-4cm diameter. Propagation: seed sown as soon as ripe at around 20°C; or rhizome division as new growth begins (very easy -- shoots emerge about 1 week after planting, 2-3 leaves within 4 weeks). Harvest: rhizome reaches best quality 3 months after planting; medicinal roots harvested from plants 4-6 years old. Edible use: rhizomes fresh or dried as flavouring, strong pungent taste like pepper and ginger combined; flowers and young shoots eaten raw, steamed, or as spice; fruits edible as a cardamom substitute. Medicinal use: rhizome is aphrodisiac, aromatic, bitter, digestive, expectorant -- used for indigestion, colic, dysentery, skin diseases, respiratory conditions and infections; applied to carious teeth for toothache relief. No known hazards listed.

How this guide is put together
The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against RHS and Met Office guidance. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
