Abutilon ‘Nabob’ short overview

Abutilon 'Nabob' is a showy flowering maple valued for its glossy, maple-like leaves, dark stems, and large, nodding deep-crimson flowers. This tender woody perennial can become a substantial shrub in frost-free climates, while gardeners elsewhere commonly grow it in a container and move it indoors for winter. Give it bright light, shelter from harsh wind, evenly moist but well-drained soil, and regular pruning to maintain a compact, well-branched shape.

Light and placement

Provide full sun to partial shade, with about 4–6 hours of direct light when grown outdoors. A south- or east-facing position is usually effective; in hot climates, give afternoon shade to reduce leaf scorch and flower stress. Too little light produces stretched stems and fewer flowers, while harsh reflected heat can scorch leaves.

Watering and humidity

Water thoroughly when the upper inch of mix begins to dry, allowing excess water to drain completely. Keep the root ball evenly moist during active growth, but reduce frequency in cool winter conditions without letting it become bone dry. Good airflow is more important than very high humidity; avoid wet foliage and standing water.

Soil and growing medium

Use a fertile, porous loam-based potting mix with reliable drainage. Keep the root zone evenly moist but never stagnant. Slightly acidic to neutral conditions are suitable; avoid compacted clay and containers without drainage holes. A peat-free or peat-reduced mix amended with compost and perlite or fine bark works well.

Feeding

Feed during active growth with a balanced liquid fertilizer at the label rate, commonly every 3–4 weeks. Water the plant first if the mix is dry, and do not fertilize a wilted, freshly repotted, dormant, or heavily stressed plant. Reduce or stop feeding during cool winter rest.

Growth and habit

This is an upright, branching shrub with comparatively fast growth in warmth and strong light. Stems can become lax or rangy when light is poor, so selective pinching and annual pruning encourage stronger branching and more flowers. Container plants usually remain smaller than plants grown year-round in mild climates.

Planting

Planting and repotting

Planting timeAfter the last spring frost; year-round for indoor containers
Planting depthSame depth as the nursery container; do not bury the stem crown
SpacingAbout 3–5 feet outdoors, depending on pruning and climate

Plant outdoors only after frost danger has passed and soil has warmed. Set the plant at the same depth as in its nursery container, firm the soil lightly, water deeply, and shelter it during establishment. In most of the United States, container culture is more reliable than permanent in-ground planting.

Repotting

Repot container plants in spring, moving up only one pot size. Refresh part of the mix annually if the plant has reached its desired container size. Handle the root ball gently and water thoroughly after repotting.

Practical tasks

Propagation and pruning

Propagation

Softwood cuttings are the most dependable method and are best taken in spring or early summer. Use short, non-flowering shoots, remove lower leaves, root in a sterile, airy medium, and maintain high humidity until rooted. Seed may be possible but will not reliably reproduce the named cultivar.

Pruning

Prune in late winter or early spring before vigorous new growth, or selectively after flowering to shape the plant. Shorten long shoots just above a healthy node and remove weak, crossing, or damaged stems. Regular pinching helps container plants stay compact; avoid severe pruning during cold, low-light dormancy.

Seasonal care

Overwintering

Before the first frost, move container plants indoors or into a heated greenhouse. Check carefully for pests, prune lightly if needed, and place the plant in the brightest available window. Keep it somewhat cooler and drier in winter, but do not expose it to freezing temperatures. Return it outdoors gradually in spring after nights are reliably mild.

Practical use

Uses

Use as a specimen, patio or balcony container plant, conservatory shrub, greenhouse subject, or sheltered wall-side accent. Its pendant flowers are ornamental and may be visited by insects. Do not promote culinary or medicinal use for this named cultivar without cultivar-specific safety and identification evidence.

Identification and habit

Appearance

The plant has glossy, broad, maple-like leaves with lobed margins and dark stems. Flowers hang singly from the leaf axils on slender stalks, creating a lantern-like display. The combination of very dark stems, deep-crimson pendulous flowers, and green lobed foliage is useful for identifying this cultivar, although flower color can vary slightly with light and temperature.

Flowering

ScentNot notably fragrant
Flower sizeLarge

The cultivar bears solitary, pendent, bowl-shaped flowers from the leaf axils. Its flowers are notably large for the group, approximately 2.4–2.8 inches across, and deep crimson to dark red. In suitable frost-free conditions flowering can extend from spring into fall; in cooler regions the season is shortened by cold.

Ecological relationships

Pollination and visitors

The deep, conspicuous flowers of Abutilon are compatible with insect visitation, and related Abutilon plants are documented as visited by bees and other insects. For ‘Nabob’ specifically, reliable evidence identifying a single primary pollinator species was not located, so visitor groups are reported cautiously.

Plant protection

Diseases and pests

Diseases

Avoid prolonged wetness and poor drainage, which can encourage root rots such as Pythium. Inspect for distorted growth or unusual mottling that may indicate viral problems. Remove affected tissue, improve air circulation, sterilize cutting tools, and avoid propagating from symptomatic plants.

Pests

Watch for whiteflies, spider mites, mealybugs, scale, aphids, and thrips, especially indoors. Check leaf undersides regularly, isolate infested plants, wash foliage, and use insecticidal soap or horticultural oil according to the label. Avoid drought stress and overcrowding, which can worsen outbreaks.

Safety and allergens

Toxicity and pollen

ToxicityUncertain; possible contact irritation

No cultivar-specific toxic principle is documented in the authoritative sources checked. However, extension guidance for Abutilon lists possible human contact dermatitis, and any plant material may cause irritation or gastrointestinal upset if eaten. Wear gloves when pruning if your skin is sensitive and do not treat the plant as edible without confirmed identification and preparation guidance.

Pollen and allergyLow airborne pollen concern
Typical season
Typically spring through fall during flowering; regional exposure varies
Pollination / pollen
Mostly insect-carried pollen; not characteristically wind-dispersed

‘Nabob’ has showy insect-pollinated flowers rather than the exposed, wind-dispersed pollen typical of major hay-fever plants. This suggests relatively low airborne pollen exposure, not zero risk; sensitive people can still react to direct contact or to pollen from an individual plant.

Dogs No cultivar-specific toxicity listing located; prevent chewing and monitor for gastrointestinal upset.
Cats No cultivar-specific toxicity listing located; prevent chewing and monitor for gastrointestinal upset.
Children No cultivar-specific poisoning evidence located; avoid ingestion and skin contact with sap if irritation occurs.
Affected plant parts All plant material should be treated as unsuitable for ingestion; sap may irritate sensitive skin.
Natural environment

Native habitat

The named cultivar is horticultural rather than a wild population, so it has no single native habitat. Abutilon is a mainly tropical and subtropical genus associated with warm climates, sun or filtered light, and soils that drain freely while retaining moderate moisture.

Good to know

Interesting fact

‘Nabob’ received the RHS Award of Garden Merit in 1993.
