About Trailing Abutilon
Abutilon megapotamicum · also called Trailing Abutilon, Flowering Maple · flowering
Native to southern Brazil, Abutilon megapotamicum is a slender, arching shrub grown for its distinctive pendulous flowers with a bright red calyx and soft yellow petals that dangle like lanterns from late spring through autumn. It thrives in full sun with a sheltered position and moist but well-drained soil, making it ideal for wall training or containers in temperate gardens. The most important care fact is consistent moisture during the growing season — plants wilt quickly if allowed to dry out. Abutilon is not listed as toxic by the ASPCA and is considered non-toxic to cats and dogs.
Preferred mix: Loam-based, well-drained
Why trailing abutilon needs this mix
Trailing Abutilon 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 trailing abutilon: 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 trailing abutilon struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives trailing abutilon 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 trailing abutilon 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 trailing abutilon?
Most flowering plants, including trailing abutilon, 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 trailing abutilon 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 trailing abutilon covers the timing and technique step by step.
