Expert tips
The key tip
Needs heat, atmospheric humidity (part shade, sheltered from wind) and rich, well-draining soil. Water generously during growth (May to October), reduce significantly in winter.
The common mistake
Neglecting it in winter (insufficient water) or giving it soil that's too compact: it becomes soft or won't flower.
The pro's trick
Divide the rhizomes in April: this quickly creates denser, more productive clumps; each segment with 2-3 buds grows well.
Seasonal watch
Autumn (August-September): this period is critical for flowering; maintain humidity and warmth, otherwise flower buds will abort.
Care
Light exposure
Place your red ornamental ginger in partial shade, ideally with a few hours of soft sunlight in early morning or late afternoon. Too much direct sun can scorch the foliage, while excessive shade will delay flowering. An exposure protected from strong winds is recommended to protect the slender stems.
Watering
Keep the soil consistently moist from May to October, the growth and flowering period. Water regularly without creating water stagnation, which would promote rhizome rot. Significantly reduce watering in winter when the plant enters dormancy.
Soil and planting
Prefer rich, well-draining, slightly acidic soil enriched with organic matter (compost, peat). The plant appreciates deep soils that allow the rhizome to develop properly. In containers, use quality potting mix for perennials or a mix of potting soil and peat.
Fertilizing
Apply balanced fertilizer every 15 days during growth (May to September). Choose a formula rich in potassium from July onwards to encourage abundant flowering. Stop fertilizing in autumn and during winter.
Pruning and maintenance
Remove spent flowers to prolong blooming and direct the plant's energy. In late autumn, when foliage yellows and withers, cut stems back to 5-10 cm from the ground. This cutting promotes winter dormancy and allows regrowth in spring.
Pests and diseases
Watch for red spider mites and scale insects, particularly in indoor or greenhouse cultivation. Excessive moisture can cause rhizome rot; improve drainage and ventilation. In the open garden, the plant is generally robust and seldom affected by diseases.
Winter storage
In cold or temperate regions, dig up rhizomes after frost and store them over winter in a cool, dry place (5-10°C), buried in sand or peat. In Mediterranean or mild regions, you can leave rhizomes in the ground by protecting the crown with thick mulch.
Did you know?
The Hedychium genus, called "butterfly ginger" in English, has been prized for centuries in South Asia for its graceful form and intensely fragrant flowers at dusk. Hedychium greenii, less well-known than its cousins H. coronarium or H. coccineum, attracts collectors with its striking red-orange inflorescences that draw butterflies and hummingbirds to tropical and subtropical gardens.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
