Anisodontea

Growing in Pots, Balconies & Indoors

Anisodontea (Cape mallow) is a compact, long-flowering shrub that the grower marks as not a houseplant but confirms grows well in containers. In a pot on a sunny patio or balcony it flowers for months; indoors it lacks the light to perform.

Quick Details

• Container Size: A small to medium pot (it stays around 50-70 cm)
• Indoor Suitability: Not a houseplant – needs full sun to flower well
• Best Spot: Full sun to part shade
• Soil & Drainage: Free-draining, light mix
• Watering in Pots: Moderate; drought-tolerant once established

Indoors & On the Windowsill

• Not a houseplant: Marked No – it flowers only in strong light, so it does not perform indoors.
• Windowsill: A very sunny sill can hold a compact plant, but expect fewer blooms than outdoors.

On a Balcony or Patio

• Light & shelter: Full sun brings the best flowering; shelter from harsh wind.
• Watering & heat: Water moderately; it tolerates some drought, but pots dry fast in summer heat.
• Overwintering: Frost-tender – move the pot under cover in cold climates.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: A small-to-medium pot with strong drainage holes; skip a standing-water saucer to avoid root rot. Terracotta breathes and dries fast, while glazed or plastic holds moisture longer.
• Potting mix: A well-aerated, organic-rich mix – peat or coir blended with perlite or vermiculite for free drainage.
• Feeding: Potted plants run their soil down fast as nutrients leach out, so feed more often than plants in open ground during active growth.
• Repotting: Refresh the mix or pot up about every two years; on established plants, lightly prune the root ball and top growth to keep them balanced.

Bloom & Flower Guide

Quick Details

• Bloom Season: Through most of the year in mild climates
• Time to First Bloom: In its first year — it flowers young and almost continuously
• Flower Appearance: Small five-petalled mallow flowers in pink, red, purple or white, each heart-shaped petal with a darker centre and fine radiating stripes
• Edibility: Grown as an ornamental that attracts pollinators; not toxic, but the flowers are not a documented food

Detailed Blooming Overview

Cape mallow is one of the longest-flowering shrubs you can grow, carrying its small hollyhock-like blooms almost year-round in mild climates. Each flower is a soft pink, red, purple or white cup with a darker eye and delicate stripes, and the plant is a steady draw for bees and butterflies.

Flower Characteristics

• Five-petalled flowers with heart-shaped petals in pink, red, purple or white, marked by a darker, striped centre.

Bloom Care & Thinning

• Encouraging bloom: Full sun and a light trim keep the flowers coming; a clip after the main flushes tidies the plant and prompts more buds.
• Pollinators: The open flowers are readily worked by bees.

Bloom Health & Protection

• Aphids and spider mites on buds: These can gather on buds and soft growth; a rinse or insecticidal soap helps.
