Thompson’s Redveined Flowering Maple (Abutilon pictum ‘Thompsonii’) short overview

Abutilon pictum 'Thompsonii' is a tender flowering maple grown for the unusual contrast between its yellow-mottled, maple-like leaves and its pendent orange to salmon-pink bell-shaped flowers. This upright evergreen shrub performs best in bright light, sheltered from harsh wind, with evenly moist but well-drained soil. In most U.S. gardens it belongs in a container, greenhouse, or protected summer display, then should be overwintered indoors before freezing weather.

Light and placement

Provide full sun to bright filtered light, ideally with morning or gentle afternoon sun and protection from harsh wind. A south- or east-facing window, bright conservatory, or sheltered patio is suitable. Too little light produces weak, stretched growth and fewer flowers; harsh reflected heat or sudden intense sun can scorch leaves, especially after indoor wintering.

Watering and humidity

Water thoroughly when the surface of the mix begins to dry, then allow excess water to drain fully. Keep the root zone evenly moist during active growth, reducing frequency in winter while avoiding complete, prolonged drought. Humidity is helpful indoors, but good airflow matters more than constantly wet foliage or saturated soil.

Soil and growing medium

Use a fertile, porous, well-drained mix with good moisture retention but no standing water. A loam-based container medium amended with compost or fine bark works well. The plant tolerates acidic, neutral, and mildly alkaline conditions, provided drainage remains reliable; avoid dense, waterlogged clay.

Feeding

Feed during active spring and summer growth with a balanced, water-soluble fertilizer at half strength every 2–4 weeks, or use a controlled-release product according to its label. Reduce or stop feeding in late fall and winter when growth and light levels decline. Do not fertilize severely wilted, freshly repotted, or dormant plants.

Growth and habit

A fast-growing, upright woody plant with a naturally bushy habit. It can become leggy in insufficient light, especially indoors, and responds well to selective pruning after flowering or in early spring. Container culture makes height, winter protection, and root-zone moisture easier to manage.

Planting

Planting and repotting

Planting timeAfter the last spring frost; year-round in frost-free climates
Planting depthPlant at the same depth as the root ball
Spacing18–36 inches

Set outdoors after the danger of frost has passed and nighttime temperatures are reliably mild. Plant at the same depth as the root ball, firm the soil gently, water thoroughly, and maintain even moisture during establishment. Space roughly 18–36 inches apart for seasonal bedding, depending on the desired fullness.

Repotting

Repot container plants in spring when roots have filled the pot, moving up only one pot size. Refresh part of the mix annually for large specimens that are difficult to shift. Ensure the container has generous drainage holes and do not bury the stem crown.

Practical tasks

Propagation and pruning

Propagation

Take softwood cuttings in spring or semi-ripe cuttings in summer. Use clean material, remove lower leaves, and root in a sterile, free-draining medium under bright indirect light and high humidity. Seed propagation is possible but may not preserve the cultivar's distinctive foliage pattern.

Pruning

Prune in late winter or early spring, or trim lightly after a flowering flush, to maintain a compact framework and encourage branching. Remove weak, damaged, or crossing shoots first. Avoid severe pruning during cold, low-light periods, when recovery indoors may be slow.

Seasonal care

Overwintering

Move containers indoors before frost or when nights approach 45°F. Place in the brightest available window, water less often, and maintain good airflow. Growth may slow substantially in winter. Check regularly for spider mites, whiteflies, scale, and mealybugs before returning the plant outdoors in spring.

Practical use

Uses

Use as a flowering container specimen, conservatory plant, sheltered patio accent, seasonal bedding plant, or warm-climate shrub. Its mottled foliage provides ornamental interest even between flowering flushes. In regions where it can escape cultivation, monitor outdoor plantings and avoid allowing unwanted spread.

Identification and habit

Appearance

The plant has smooth, maple-like palmate leaves with three to nine toothed lobes and a distinctive yellow-green mottled pattern. Flowers hang singly from leaf axils and branch tips on slender stalks. The upright woody framework can resemble a small tree when trained to one main stem, or remain bushier when pinched.

Flowering

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
Flower colors
Orange to salmon-pink with darker veins
Flower form
Pendent bell-shaped flowersFlower form
ScentNo notable fragrance
Flower sizeMedium; about 1–2 inches across

Solitary, pendent flowers arise from the leaf axils and branch tips. The five-part, bell-shaped corollas hang on long stalks and show orange to salmon-pink coloring with darker veining. Blooming is most reliable from spring through fall when plants receive strong light, warmth, regular water, and periodic feeding.

Ecological relationships

Pollination and visitors

The pendent, nectar-bearing flowers are documented as attractive to hummingbirds and butterflies, with broader flowering-maple references also noting insect visitors. Specific pollinator species for this cultivar were not established. Flower visitors may be most frequent in warm, bright conditions when blooms are abundant.

Plant protection

Diseases and pests

Diseases

Watch for virus symptoms beyond the characteristic cultivar mottling, root problems in persistently wet soil, and occasional honey fungus in susceptible outdoor settings. Reduce disease pressure with clean tools, good air circulation, sterile propagation material, and careful watering. Remove severely declining plants rather than composting diseased tissue.

Pests

Inspect leaf undersides and new growth for whiteflies, spider mites, mealybugs, scale, and aphids. Isolate infested container plants, rinse foliage when appropriate, and improve airflow. Use insecticidal soap or horticultural oil according to the product label, avoiding treatment during high heat or when pollinators are actively visiting flowers.

Safety and allergens

Toxicity and pollen

ToxicityNo confirmed toxicity classification located

No authoritative, cultivar-specific toxicology record was located for Abutilon pictum 'Thompsonii'. Major companion-animal poison lists do not identify it as a commonly reported toxic plant, but absence from a database is not proof of complete safety. Prevent children and pets from chewing ornamental plant material, and seek professional advice after significant ingestion.

Pollen and allergyLow airborne allergy relevance
Typical season
Spring through fall where grown outdoors
Pollination / pollen
Heavy, animal-transferred pollen

This is an insect-pollinated flowering shrub rather than a wind-pollinated plant, so its pollen is not typically released in large airborne clouds. Direct allergy data for this exact cultivar were not located; people with strong pollen sensitivity should still avoid rubbing flowering parts and should monitor personal reactions.

Dogs No specific toxicity record found; avoid ingestion
Cats No specific toxicity record found; avoid ingestion
Children No specific toxicity record found; avoid ingestion
Affected plant parts No toxic part has been established; do not encourage consumption
Natural environment

Native habitat

The species complex is associated with warm South American environments, particularly Brazil and neighboring regions, and is cultivated widely in tropical, subtropical, and protected temperate settings. It prefers bright conditions, fertile soils, regular moisture, and shelter from freezing temperatures and drying winds.

Good to know

Interesting fact

The cultivar's yellow-green leaf pattern is associated with Abutilon mosaic virus.
