A trailing false violet
Streptocarpus saxorum, sometimes called the false African violet, is an evergreen perennial with trailing stems and small, fleshy, velvety, rounded leaves. Solitary pale mauve flowers with white throats open in the leaf axils, each about 3cm across.

Rooted in East Africa
This species belongs to the Gesneriaceae family and hails naturally from Kenya and Tanzania, where its relatives in the genus Streptocarpus grow as annuals, perennials or subshrubs across similar habitats.

Bright, sheltered, steadily watered
Grow it in free-draining compost on an east- or west-facing windowsill, or in a temperate to warm greenhouse with bright filtered light and shade from hot sun, in a sheltered spot with moist but well-drained soil. Through the growing season water freely but let the compost dry between waterings, feeding fortnightly with a high-potassium fertiliser, then water sparingly in winter as the compost dries. It tolerates chalk, clay or sandy soils across acid, neutral or alkaline pH, though it is only hardy to H1C and needs frost-free conditions.

From seed or leaf
This species can be increased from seed or from leaf cuttings, the same methods used across the wider Streptocarpus genus.

Trailing habit, modest flowers
It grows low and spreading, reaching only 20 to 50cm in height and spread, with a trailing habit suited to hanging pots. The rounded, velvety leaves and solitary pale mauve, white-throated flowers set it apart from the more upright, larger-leaved Streptocarpus hybrids grown for cut-flower type displays.

Sap-suckers to watch
Glasshouse leafhoppers, mealybugs, thrips, vine weevil and tarsonemid mite are the pests most likely to trouble this plant.

Grey mould and mildew
The main diseases to watch for are grey mould, or botrytis, and powdery mildew.

Little pruning needed
This plant asks for no routine pruning, making it a low-fuss trailing houseplant once its light and watering rhythm is settled.
