Begonia Black Mamba Overview
Begonia ‘Black Mamba’ is a striking rex-type begonia known for its dramatic, dark‑purple to near‑black foliage with contrasting silver or deep green veins and a compact, mound‑forming habit. Valued for bold color and texture, it performs best in bright, indirect light and high humidity — perfect for statement pots, terrariums, or shaded display areas where its foliage provides strong visual contrast.
Why Choose This Plant?
| Dramatic, almost-black leaves and striking patterning create an eye-catching centerpiece. Compact growth makes it ideal for tabletops, shelves, and terrariums; rewarding for collectors and those seeking high-impact foliage without large space requirements. |

Care Guide
| Light | Bright, indirect light or filtered shade; avoid direct sun which can scorch or fade leaf pigmentation. Too little light dulls color and slows growth. |
| Water | Keep the mix lightly moist but not soggy; allow the top 1–2 cm to dry between waterings. Water gently at the soil level to protect leaves from spotting and rot. |
| Humidity | Prefers high humidity (60%+); benefits from pebble trays, humidifiers, or placement in bathrooms/terrariums. Avoid prolonged wet leaf surfaces to prevent fungal issues. |
| Temperature | Ideal 18–24°C (65–75°F); keep above ~15°C (59°F) and protected from cold drafts and sudden drops. |
Use a well-draining, humus-rich mix (peat or coco with perlite and bark). Repot when root-bound; avoid overpotting. Feed lightly with a balanced, diluted fertilizer during spring and summer.
Use in Terrariums
| Well-suited to large, open or semi-open terrariums with high humidity and good airflow; avoid small fully sealed containers that remain overly wet. Its compact habit and bold foliage make it an excellent focal plant for humid displays. |
