Begonia blancii ‘Mottled’ is a rare and visually enchanting species admired for its intricate leaf patterning, compact form, and luminous foliage. Native to the Philippines and part of the Begoniaceae family, this cultivar is celebrated for its distinctive mottled markings that give each leaf a painterly, almost ethereal quality.

The leaves are small to medium-sized and typically ovate with a slightly glossy, succulent-like texture. Their surface shimmers with patches and flecks of creamy white, pale green, and soft lime scattered across a deep emerald backdrop. The fine speckling and mottling vary from leaf to leaf, giving every plant its own unique character. The leaf margins may be subtly scalloped, adding a gentle, decorative finish.

Begonia blancii ‘Mottled’ grows in a tidy, compact mound with short internodes and bright green stems that hold the foliage close and full. Its luminous patterning and delicate form make it a favourite among terrarium enthusiasts, rare plant collectors, and anyone looking for a small but striking foliage plant.

Begonia blancii ‘Mottled’ – Care Guide

Light

Prefers bright, indirect light to maintain clear mottling and rich green tones. Tolerates medium light but may develop softer or less pronounced markings. Avoid direct sunlight, which can scorch delicate leaves.

Watering

Keep the soil lightly moist, allowing the top 1–2 cm to dry between waterings. Begonia blancii dislikes soggy conditions but should not be allowed to dry out completely. Use room-temperature filtered or rainwater to prevent leaf spotting.

Temperature and Humidity

• Temperature: Thrives in warm conditions between 18–26 °C. Avoid cold draughts and temperatures below 15 °C.

• Humidity: High humidity (60–80%) helps maintain leaf quality and vibrancy. Ideal for terrariums, display cabinets, or rooms with naturally higher moisture.

Soil and Potting

Use a light, airy, fast-draining mix such as a blend of peat-free compost, perlite, and fine bark. Avoid compact soils. Repot every 1–2 years in a shallow pot to suit its small root system.

Feeding

Feed every 3–4 weeks during spring and summer with a weak, balanced liquid fertiliser. Overfertilising can damage the delicate roots.

Pruning and Maintenance

Remove any yellowing or damaged leaves to maintain a neat appearance. Pinch back lightly if the plant becomes leggy. Avoid overhead watering to reduce the risk of fungal spotting.

Growth and Maturity

A compact, moderate grower that typically reaches 10–20 cm in height and spread. Forms a dense clump with tightly spaced leaves and an attractive bushy habit.

Common Issues

• Leaf spotting: Caused by water sitting on the leaf surface.

• Crispy edges: Low humidity or underwatering.

• Yellow leaves: Overwatering or poor drainage.

• Pests: Watch for fungus gnats in overly moist soil and mealybugs on leaf undersides.

Background and Benefits
