Description
A colorful foliage plant with thick, glossy leaves splashed in yellow, orange, red, green, and burgundy. It looks tough, but indoors it can be dramatic after moves, cold drafts, or missed waterings.
Care
- Light: Bright light is essential for color. Some gentle direct sun helps.
- Water: Keep lightly, evenly moist; avoid both bone-dry crashes and soggy soil.
- Soil & potting: Rich but well-draining mix.
- Humidity & temperature: Likes warmth and humidity. Avoid cold windows and vents.
- Feeding: Light feeding spring-summer.
- Repotting / propagation: Avoid unnecessary disturbance; crotons drop leaves when stressed.
Propagation
From stem cuttings in warmth and humidity. Cuttings root slowly; use a node, keep the medium just moist, and wash off irritating sap. See Propagation Basics.
Toxicity
Toxic to cats and dogs. ASPCA lists croton as toxic; sap and chewed leaves can irritate the mouth and stomach.
