Returns Simplified.Begonia maculata Black Forest is a rare and striking cultivar of the Polka Dot Begonia, part of the Begoniaceae family and native to the tropical forests of Brazil. While the classic Begonia maculata is admired for its olive-green leaves with white polka dots, the Black Forest variety intensifies the drama with darker foliage and bolder contrast.
The leaves are long, asymmetrical, and wing-shaped, with an upper surface in deep green to nearly black, decorated with prominent silver-white spots. The undersides are a rich burgundy red, creating a striking two-tone effect that stands out in any plant display. When mature, clusters of delicate white flowers with yellow centres appear, contrasting beautifully with the dramatic leaves.
Growing to around 60100 cm tall indoors, Begonia maculata Black Forest is an upright cane begonia, forming a bushy, architectural plant with stems that resemble bamboo canes. Its combination of unusual foliage and seasonal flowers makes it both exotic and elegant a true showpiece houseplant.
Thrives in bright, indirect light. Too much direct sunlight may scorch the dark foliage, while too little light will reduce spotting and slow growth.
Water when the top 23 cm of soil feels dry. Keep the soil evenly moist but never waterlogged. Allow excess water to drain freely, as begonias are prone to root rot if kept in soggy soil. In winter, reduce watering slightly.
Temperature: Best in 1826C. Protect from cold draughts and avoid prolonged exposure below 15C.
Humidity: Prefers high humidity (60%+). Mist occasionally, use a pebble tray, or place near a humidifier. In dry air, leaf edges may crisp.
Use a light, free-draining peat-free compost. A mix with added perlite or orchid bark works well. Repot every 12 years in spring, being careful with delicate roots and stems.
Apply a balanced liquid fertiliser every 23 weeks during spring and summer. Stop feeding in winter when growth slows.
Pinch back stems to encourage bushier growth. Remove any dead or damaged leaves promptly. Older canes may be cut back to promote new growth from the base.
A moderate to fast grower in the right conditions, reaching 60100 cm tall with an upright, cane-like habit. Produces clusters of white flowers in spring or summer.
Crispy leaf edges: Low humidity.
Yellowing leaves: Overwatering or poor drainage.
Pale foliage/loss of spots: Insufficient light.
Pests: Susceptible to spider mites, mealybugs, or aphids.
Cane begonias like Begonia maculata Black Forest have long been admired for their ornamental foliage and upright form. This cultivar is particularly desirable for its darker leaves, dramatic contrast, and seasonal blooms. As an indoor feature plant, it adds instant exotic appeal to modern and tropical-inspired interiors.
