What Is Red Button Ginger and Where Does It Come From?
Costus woodsonii, commonly known as red button ginger or scarlet spiral-ginger, is a rhizomatous herbaceous perennial native to humid forests and coastal scrublands along the Caribbean coasts of Nicaragua, Costa Rica, and Panama to Colombia. It forms spiraling stems topped with glossy, overlapping bright red bracts from which small red-and-yellow tubular flowers emerge, blooming almost continuously in warm, humid climates. Popular as a tropical garden accent and container plant, it thrives in bright indirect light to partial sun and evenly moist, well-drained, organically rich soil.
How to Propagate Red Button Ginger?
Rhizome division
Divide during the warm growing season for fastest recovery, and keep newly divided plants in bright, indirect light with consistent moisture until established.
- 1 Carefully unearth a healthy clump with at least 2-3 stems and visible roots attached.
- 2 Use a clean, sharp knife or pruners to divide the rhizome into sections, each with roots and at least one stem.
- 3 Let cut surfaces air-dry for a few hours to callus before replanting.
- 4 Plant each division in moist, well-draining, organically rich soil at the same depth as before.

What Diseases Commonly Affect Red Button Ginger?
TLDR: Red Button Ginger is susceptible to 6 known diseases. Monitor regularly for early detection.
Pythium Root Rot
Pythium root rot is a serious fungal disease caused by various Pythium species including P. aphanidermatum, P. ultimum, and P. irregulare. These water molds are present in practically all cultivated soils and attack plant roots under wet conditions, causing rapid wet rot that can extend into the stem. The disease is favored by poor drainage, overwatering, and specific temperatures depending on the species.
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Fusarium Wilt
Fusarium wilt is a serious fungal disease caused by the soil-borne fungus Fusarium oxysporum. The fungus invades roots and blocks the water-conducting vessels (xylem) of the plant, causing progressive wilting and eventual death. Host-specific forms of the pathogen exist that attack different plant species.
Scale Insects
Scale insects are small sap-sucking pests that appear as brown, shell-like bumps on plant stems and leaves. There are over 25 species, divided into armored (hard) and unarmored (soft) scales. They feed by piercing plant tissue and extracting sap, which weakens the plant and can lead to yellowing, stunted growth, and even death if left untreated. They also excrete honeydew, which attracts ants and promotes sooty mold growth.
Fun Facts
The showy red buttons are actually bracts, not the true flowers - small yellow-and-red tubular flowers peek out one or two at a time.
It belongs to the ginger order Zingiberales but forms its own family, Costaceae, distinguished by a single spiral row of leaves.
In its native Central American coastal range, it tolerates salt spray and sandy soils.
