During the growing season it produces stunning pink or white and off-white flowers. This species is considered a deciduous plant, and will lose much of its foliage during the dormant season.

Though this plant is typically grown in USDA Zone 9-11, a mature plant can be cold hardy at least to 30°F for a short time. In colder regions, this plant has to be grown in a protective pot placed in locations sheltered from extremely cold temperatures. Make sure the soil for Curcuma alismatifolia is kept moist to ensure growth and it should be well drained. Additionally, the pot should be lined with a plastic layer to protect from frost. If a container is used, the soil can dry out more quickly so it is important to check the soil regularly. When watering, make sure to water the soil and not the foliage. During the hottest months it may need water every day, as the heat can dry out the soil rapidly.
