Wax Begonia
Begonia x semperflorens-cultorum
Compact, mounding herbaceous plants with succulent, glossy green or bronze leaves that are rounded and slightly waxy. They produce small clusters of four-petaled flowers.
- Light
- Partial shade to full shade. In cooler climates, they can handle full morning sun, but intense afternoon sun can scorch the leaves.
- Water
- Water when the top inch of soil feels dry. They prefer even moisture but are susceptible to root rot if overwatered. Avoid getting water on the leaves to prevent fungal issues.
- Growth
- Mounding perennial (often grown as an annual); typically reaches 6-12 inches in height and spread.
Care instructions
Provide bright indirect light or morning sun with afternoon shade. Keep soil consistently moist but never soggy. Feeds every 2-4 weeks with a balanced liquid fertilizer during the growing season.
