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.

Mature size: 1–3 m tall and 1–1.5 m wide outdoors in frost-free climates; typically 60–120 cm as a container specimen with annual pruning.

Indoor size vs how big it gets in the wild

Painted Flowering Maple is a tree at heart. Indoors a pot and your ceiling keep it to 1–3 m tall and 1–1.5 m wide outdoors in frost-free climates, but in the ground it is a different scale of plant entirely (typically 60–120 cm as a container specimen with annual pruning.). Indoors and in a pot, expect 1–3 m tall and 1–1.5 m wide outdoors in frost-free climates. In the ground with no restriction it is a completely different plant — typically 60–120 cm as a container specimen with annual pruning. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Growth rate and years to mature

Painted Flowering Maple is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: feed monthly with a balanced liquid fertiliser during the growing season from spring to early autumn; a high-potash feed in summer encourages heavier flower production.

Want this turned into the right next pot at the right moment? The pot size calculator and the painted flowering maple repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast painted flowering maple grows.

How to keep painted flowering maple smaller

You are not stuck with the maximum size. For painted flowering maple specifically, these are the levers, in order of impact:

The decisive tool is the secateurs: painted flowering maple can be topped (cut the main growing tip) to cap its height and force a bushier, shorter shape.
Keeping it deliberately pot-bound in a snug container slows the whole plant and limits ultimate size.
Prune in spring so it heals fast; remove the tallest leader back to a node to reset the height.
Expect to top or hard-prune it every year or two — left alone it heads for the ceiling.

The keep-it-smaller method, step by step

Pick the new height. Decide how tall you want painted flowering maple and find a leaf node or branch point just below that.
Top the main stem. Cut the main growing tip cleanly just above that node in spring; this permanently caps the height and forces side branches.
Keep the pot snug. Avoid jumping to a much bigger pot — a slightly restricted rootball keeps the whole plant smaller.
Maintain the shape. Prune back the tallest new leaders each spring to hold it at the height you chose.

How to grow painted flowering maple bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for painted flowering maple the accelerators are:

It already wants the bright light it needs; warmth, a yearly pot-up and spring-summer feed are the accelerators.
Pot up a size every year or two while young; restricted roots are the main thing holding height back.
Feed regularly through the growing season and keep it warm — height comes from sustained good conditions.

Light is almost always the ceiling. The painted flowering maple light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When painted flowering maple outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for painted flowering maple:

The top leaves pressing against or bent by the ceiling — the classic "this is now too tall indoors" sign.
It has to be moved away from a light source it has literally outgrown.
Roots filling the largest pot you can reasonably keep indoors — at that point it is top-or-prune or move it outside (if hardy).

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the painted flowering maple repotting guide. If you want more of this plant instead of a bigger one, the painted flowering maple propagation guide turns prunings into new plants.

Painted Flowering Maple size — frequently asked questions

How big does painted flowering maple get?

Painted Flowering Maple reaches 1–3 m tall and 1–1.5 m wide outdoors in frost-free climates when grown indoors, and far larger where it grows unrestricted (typically 60–120 cm as a container specimen with annual pruning.). It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Is painted flowering maple slow or fast growing?

Painted Flowering Maple is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Painted Flowering Maple is a tree at heart. Indoors a pot and your ceiling keep it to 1–3 m tall and 1–1.5 m wide outdoors in frost-free climates, but in the ground it is a different scale of plant entirely (typically 60–120 cm as a container specimen with annual pruning.).

How long does painted flowering maple take to reach full size?

Roughly two to four years from a young plant to a room-filling specimen in good light. Light, pot size and feeding move that timeline more than anything else.
