Plant Information Sheet
African Violet
Streptocarpus ionanthus · formerly Saintpaulia ionantha
Identification
A low rosette of rounded to oval, softly hairy leaves surrounds clusters of five-lobed flowers. Cultivars vary greatly in flower color, leaf shape, size, and variegation.
Care
Light
Use bright filtered light. Strong afternoon sun can scorch leaves; very low light reduces flowering and produces stretched growth.
Water
Water when the surface begins to dry. Use room-temperature water and drain the pot completely. Avoid leaving water on fuzzy leaves, especially in cool conditions.
Temperature and humidity
Normal warm indoor temperatures are suitable. Moderate humidity helps, but the crown and roots still need air movement.
Standard soil mix
Use two parts fine potting mix, one part perlite, and one part vermiculite or fine bark. The mix should retain modest moisture while remaining airy. Use a small pot with an open drainage hole.
Flowering
Consistent light is the main driver of repeat bloom. Feed lightly during active growth with a balanced fertilizer, following its label. Remove spent flowers without damaging the crown.
Propagation
Root a healthy leaf with its petiole in a lightly moist, airy medium. New plantlets form near the petiole base. Crown division is possible on multi-crowned plants.
Seed germination and light
Surface sow the tiny seeds on moist, fine seed-starting mix and leave them uncovered. Provide bright indirect light or a white grow light on a 12-hour light and 12-hour dark cycle. Keep the surface moist under a clear cover; avoid direct sun and overheating.

Environment and native habitat
Wild relatives occupy shaded, humid rock faces and forested slopes in tropical East Africa. Indoors, bright filtered light, an airy root zone, steady warmth, and moderate moisture recreate the useful parts of that environment.

Climate lessons for African Violet
Climate sets the limits for water use, seasonal growth, and outdoor survival.
Lafayette translation
Warm, humid tropical conditions with no frost. Indoors in Lafayette, protect it from cold glass, dry furnace air, and sudden temperature swings.
Care principle
Reproduce the function of the native setting rather than copying a watering calendar. Check light, temperature, root-zone air, drainage, and the plant’s current growth before acting.

How African Violet works in its habitat
Its form and life cycle reflect relationships with water, light, substrate, and animals.
Ecological relationships
Low forest light and moist rock habitats favor compact leaf rosettes. Flowers serve visiting insects; leaf propagation allows vegetative reproduction in cultivation.

Environmental Information Sheet
Native environment of African Violet
Streptocarpus ionanthus comes from the Usambara Mountains of Tanzania and grows primarily in wet tropical forest and shaded rock faces.
What this means in cultivation
Bright filtered light, an airy organic root zone, and steady moisture without saturation reproduce the useful features of its shaded, humid native setting.
