Costus woodsonii, or Red Button Ginger, is a beautiful and colorful plant that is native to Central America. It is a small shrub that grows to a height and width of 2-5 ft and is suitable for USDA Zone 9-11. This plant requires semi-shade and moderate water to grow and thrive, but it is sensitive to over-watering and can be easily damaged by cold winter weather. Therefore, it is important to provide the appropriate care for this plant, particularly during colder temperatures.
One way to ensure successful growth is to use a pot with sufficient drainage and a soil that is not too demanding. The plant can also thrive in pots when given the proper care. When placed outdoors, it prefers a full sun position but can tolerate some shade. The soil should be well-draining and slightly damp, but not waterlogged. The Red Button Ginger is known for producing beautiful red, crimson, and vinous flowers throughout the year, as well as yellow and orange flowers in the winter. However, it is not frost-tolerant and may stop blooming and appear less vibrant when exposed to frost.
In addition to its decorative qualities, the Red Button Ginger also has edible yellow flowers that emerge from red cones. If you are interested in growing this plant, be sure to provide the necessary care and protection to ensure its success.
