Abutilon, flowering maple, is a mostly shade-lowing outdoor plant and a handsome house plant. It is content to live indoors all year if the right light is given. Outdoors it grows best where there is little to no frost in winter.

Abutilon has a multitude of flowers shaped like small hollyhocks. Flowers are pendulous, bell- or cup-shaped growing 2 to 3 inches (5-7.6cm) long and wide, sometimes larger. Flower colors include yellow, orange, red, pink, apricot, purple-red, and white.

Abutilon leaves are simple or lobed and maplelike–thus the common name flowering maple.

Abutilon is fast growing. For best flowering and to keep plants bushy, it is best to pinch back new growth once six leaves appear. Abutilon is best grown in a sheltered spot in the garden. Some species also can be grown in pots or hanging baskets.

  • Grow abutilon in humus-rich, well-drained soil.
  • Where abutilon is marginally hardy, choose a site against a south-facing wall for winter protection.
  • In cold-winter regions, grow abutilon in containers and overwinter them indoors in a bright, cool spot.
  • Grown indoors, abutilon prefers average indoor temperatures (65° to 70°F/16°-21°C) and humidity; a difference of 10°F between day and night temperatures is ideal.
  • Grow indoors in standard indoor potting soil.
  • Abutilon prefers a soil pH of 5.5 to 6.3.

When to Plant Abutilon

  • Start abutilon from seed indoors in late winter or early spring. Sow seed 4 to 6 weeks before the last frost in spring.
  • Start abutilon from softwood cuttings in autumn to set outdoors the following spring.
  • Grow outdoors in subtropical regions. Indoors plant should be 4 hours of direct sunlight each day.

Planting and Spacing Abutilon

  • Space abutilons 5 to 10 feet (1.5-3m) apart outdoors.
  • Start seed or cutting indoors; plant in clean seed starting mix or potting soil. Keep the medium evenly moist at 65° to 70°F (18°-21°C) until plants are well-rooted.
  • Sow seed 1/8 to 1/4 inch deep.

How to Water and Feed Abutilon

  • Abutilon likes plenty of moisture; keep the soil evenly moist. Allow the soil to dry out somewhat between watering .

Abutilon Care

  • Cut abutilon back by one-third in winter to ensure bushier plant in spring.
  • Repot in late winter if needed. Stake for upright growth.
  • Abutilon is a vigorous, fast-growing plant; to produce bushy plants, pinch off the tips of growing branches frequently. Pinch heavily in autumn for better late winter and early spring bloom.
  • Yellowing leaves are to be expected; remove them as they appear.
  • Prune plants to shape in late winter or early spring; cut them back hard if they become rangy.
  • Young plants bloom best; consider removing old plants when they become woody.
  • In winter, protect abutilon with straw or bracken.

Growing Abutilon as a Houseplant

  • Three species, Abutilon hybridum, A. megapotamicum, and A. pictum are often grown as houseplants.
  • Grow Abutilon in direct light in a warm room that has medium humidity.
  • Keep the growing medium evenly moist from spring to fall; allow the medium to dry out between waterings.
  • Cut the stems back in spring before new growth stats, and pinch out growing tips to keep the plant compact.
  • Fertilize Abutilon every two weeks when the plant is in growth in in flower.
  • Repot in spring when necessary.

Pruning Abutilon

  • Cut out frost-damaged and dead wood in spring.
  • Cut back the previous season’s growth by two-thirds of their length.
  • Pinch out the tips of free-standing specimens in the growing season if necessary to encourage bushiness.

Abutilon Pests and Diseases

  • Scale, red spider mites, mealybugs, and whiteflies occasionally present a problem particularly when abutilon is grown indoors.
  • Root knot nematodes, leaf spot, and virus can damage Abutilon.

Abutilon Propagation

  • Take tip cuttings at any time or grow plants from seed. Take cuttings in spring to propagate for garden use or in late summer to overwinter plants.
  • Take cuttings every other year to grow new plants to replace old woody plants.
