How Do You Grow Hedychium Coronarium?
Size & Growth
Hedychium coronarium can grow approximately 5’’ feet high and have a 5’ foot spread. The individual stems grow upright at a fast rate and start covering the area around it.
The foliage consists of large, lance-shaped leaves, around 24” inches long and 5” inched wide. The leaves are medium to bright green in color.

The flowers are sweetly fragrant and are often used to make perfumes. The petals make up an intricate shape similar to the shape of a butterfly.
Hence, various common names have the word butterfly in them.
Light & Temperature
These flowering ginger lilies are winter hardy to USDA Hardiness Zones 8-10.
They prefer hot and humid summers and subtropical climates over cooler climes. They need to be overwintered indoors to prevent root damage.
As for light, the white garland lily thrives in full sun but will tolerate part shade.
Watering and Feeding
The garland flower has medium to wet water needs, meaning they need to be watered frequently in hot and dry summers. Don’t let the soil dry out completely as it can cause damage to the plant.
These plants crave nutrition and organic matter, so make sure to supplement your soil during the growing season if it’s not organically rich. Feed the plants with organic compost or organic fertilizer as needed.
If growing in containers place the ginger plant type near a water garden or pond periphery for extra humidity.
Soil & Transplanting
Besides having good moisture retention, the soil should also be organically rich, moist, and well-drained. The soil shouldn’t be too alkaline. The pH should be near neutral or slightly acidic.
As for transplanting, Hedychium coronarium plants respond well to being moved. Divide the new shoots and plant them in the ground in permanent locations in shaded locations.
Grooming and Maintenance
When it comes to pruning, the plant has no needs requiring compulsory cutting.
However, you have to be careful about winters. Overwinter coronarium indoors in a dry, frost-free location.
Be careful about root rot, keeping the soil well-drained. Otherwise, the Hedychium is pretty low-maintenance in the garden.
NOTE: The Heliconia plant grows much like Hedychium gingers. And don’t forget the Curcuma plant, Zingiber officinale or Zingiber Zerumbet.
