About Painted Flowering Maple

Abutilon pictum · also called Painted Flowering Maple, Redvein Abutilon · flowering

Abutilon pictum is a fast-growing evergreen shrub native to Brazil and Argentina, grown widely for its pendulous bell-shaped orange-yellow flowers with prominent deep red veins and its attractive maple-like lobed leaves. The most commonly grown form, 'Thompsonii', features striking yellow-mottled variegated foliage caused by Abutilon mosaic virus. It thrives in a bright, sheltered position and flowers almost year-round in warm conditions; the key care requirement is a minimum winter temperature above 5°C, making it a conservatory or houseplant in most of the UK. Abutilon is not listed on the ASPCA toxic plants database and is not considered toxic to cats or dogs, though mild gastrointestinal upset may occur if large quantities are consumed.

Ideal humidity: Moderate (40–60%)

Watch for — Whitefly (Trialeurodes vaporariorum): One of the most common pests on Abutilon, especially under glass; clouds of tiny white insects under leaves produce honeydew and sooty mould, and weaken the plant. Use yellow sticky traps, introduce Encarsia formosa as biological control, or spray with insecticidal soap ensuring full coverage of leaf undersides.

The watering schedule, season by season

Painted Flowering Maple flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for painted flowering maple is water when top 1–2 cm of compost dries; less in winter, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.

Keep compost evenly moist during active growth but never waterlogged; water when the top centimetre dries out. In winter, reduce watering substantially — allow the compost to become almost dry before rewatering to prevent root rot.

Seasonal and environmental adjusters

Yellowing leaves, bud drop, and a heavy, constantly wet pot. Mushy stems or crown rot at soil level. Fungus gnats and a sour soil smell. Erratic watering — bone dry then flooded — makes painted flowering maple drop its buds and flowers. Consistency through the budding period is what protects the display.

What are the signs of an underwatered painted flowering maple?

Wilting, bud and flower drop, and crispy leaf edges. A faded, stressed look and a rootball that has pulled from the pot sides.
