Begonia heracleifolia · Star Begonia (Mapleleaf Begonia)

The plant shows deeply lobed, star/palmate-shaped leaves with 5-9 pointed lobes radiating from a central point, consistent with the common name 'star begonia' given to B. heracleifolia. The leaf surface shows dark green coloration with reddish-maroon tones and lighter green along the veins, a pattern typical of this species and its cultivars. The leaf margins are serrated/toothed and appear to have fine hairs (pubescence) along the edges and veins, which is characteristic of B. heracleifolia's rhizomatous begonia group. The growth habit is clumping/mounding from what appears to be a rhizomatous base, matching this species' typical form. Similar species to rule out would include other rhizomatous begonias like B. bowerae or hybrid 'Rex' type begonias, but the strongly star-shaped leaf lobing with this particular vein pattern and coloration most closely matches B. heracleifolia or one of its many cultivars (e.g., 'Nigricans', 'Pewter'). Without seeing flowers or a clearer close-up of leaf texture/hair density, I can't rule out a closely related cultivar with full certainty, so I'm marking this as probable rather than certain.

Light

Medium to bright indirect light; some morning sun is fine but protect from harsh midday direct sun which can scorch the patterned leaves.

Water

Allow the top inch or so of soil to dry out between waterings, roughly every 7-9 days; this rhizomatous begonia is more drought-tolerant than wax begonias and dislikes soggy soil.

Nutrients

Feed with a balanced liquid fertilizer diluted to half strength every 4 weeks during spring through fall; withhold in winter.

Repotting

Repot every 1-2 years in spring, or when the rhizome outgrows the pot -- it tends to grow along the soil surface and spread outward.

Soil media

Well-draining potting mix amended with perlite and some organic matter (peat or coir); good aeration matters more than richness.

Temp & humidity

65-75F with moderate to high humidity (50-60%); appreciates a pebble tray or humid conservatory room but avoid wetting the fuzzy leaves.

Temperature range

🌡️ 65-75F

Humidity range

💦 50-60%

Care group

🏷️ Medium Light & Moderate Humidity

Toxicity

Contains soluble calcium oxalates; mildly toxic if ingested by pets or people, causing mouth/GI irritation -- keep away from curious pets and small children.

Pests & diseases

Watch for powdery mildew and botrytis in stagnant humid air, and mealybugs or spider mites in dry conditions; good air circulation prevents most fungal issues. Root/rhizome rot can occur if overwatered.

Propagation

Rhizome division is easiest -- cut sections with roots and a growing point attached and pot separately; can also propagate via leaf or petiole cuttings in moist soil mix.
