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.
Preferred mix: Fertile, moderately rich, well-drained
Why painted flowering maple needs this mix
Painted Flowering Maple flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.
- Flowering is expensive for painted flowering maple: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
- A loam-based mix holds nutrients and water far more evenly than a light peat mix, which means a longer, more reliable flowering period.
- It still needs sharp drainage — most flowering plants resent cold, wet feet far more than they resent being a little lean.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons painted flowering maple struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives painted flowering maple weak growth and few, short-lived flowers — it simply runs out of fuel.
- A heavy, badly drained soil rots the roots or crown, often over a wet winter, and you lose the plant before it ever flowers again.
- Over-rich, high-nitrogen mixes can push lush leaf at the expense of flowers — balance, not excess, is the aim.
Either starving painted flowering maple in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.
pH — does it matter for painted flowering maple?
Most flowering plants, including painted flowering maple, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A quality bagged compost works for painted flowering maple in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
Drainage and the pot
Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.
For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for painted flowering maple covers the timing and technique step by step.
