Begonia x hiemalis (Begonia elatior) 丽格海棠 (15cm pot)

Begonia x hiemalis, commonly known as the Begonia elatior, is a beautiful hybrid plant that has been cultivated for its stunning, showy flowers and attractive foliage. This compact, evergreen perennial is a popular ornamental plant, often grown as a houseplant or in sheltered outdoor spots. Originating from the hybridisation of species within the Begonia genus, it is known for its bright, vibrant blooms in colours ranging from red, pink, orange, and white, often appearing in clusters above the foliage. The leaves are typically dark green with a slightly serrated edge, providing an attractive contrast to the colourful flowers. Begonia x hiemalis thrives in warmer climates, offering long-lasting blooms for several months, making it a favourite for both beginner and experienced gardeners alike.

Plant Care Guide

Light: Begonia x hiemalis prefers bright, indirect light. Direct sunlight can scorch the delicate leaves and flowers, so it’s best to place the plant in a location where it receives filtered light or in partial shade. Too little light can result in poor flowering and leggy growth. A well-lit room or a shaded patio spot with dappled sunlight is ideal for this begonia.

Water: Begonia x hiemalis enjoys consistently moist soil but dislikes standing water. Water the plant thoroughly when the top 2–3 cm of soil feels dry, but ensure that the pot has good drainage to prevent waterlogging. Overwatering can lead to root rot, so avoid letting the plant sit in water. During periods of active growth, keep the soil evenly moist. In contrast, reduce watering slightly during the dormant phase, but never let the soil dry out completely.

Soil: This begonia thrives in well-draining, rich, organic soil. A general-purpose potting mix with added perlite or vermiculite will provide the ideal texture for drainage and moisture retention. For container planting, ensure the pot has adequate drainage holes to allow excess water to escape. Avoid heavy, water-retentive soils, as these can cause root rot.

Fertilising: Begonia x hiemalis benefits from regular feeding during the growing season to support its vigorous flowering and lush foliage. Use a balanced liquid fertiliser diluted to half strength. Fertilising too frequently or with a fertiliser that is too strong can cause leaf burn, so always follow recommended guidelines.

Common Pests: While Begonia x hiemalis is relatively pest-resistant, it can occasionally be affected by common indoor pests such as aphids, mealybugs, and spider mites. Keep an eye out for sticky residue, small webs, or visible insects on the leaves and stems. If pests are detected, treat the plant with insecticidal soap or neem oil. Additionally, watch for fungal diseases like powdery mildew in overly humid conditions. Ensure good air circulation around the plant to help prevent these issues.

General Care: Begonia x hiemalis is a low-maintenance plant when given the right care. Regularly remove dead or damaged flowers and leaves to encourage new growth and maintain the plant’s attractive appearance. This plant prefers to be kept in a humid environment, so misting the leaves occasionally or placing it near a humidity tray can help replicate these conditions. However, avoid over-wetting the foliage, as this can encourage fungal infections.
