First identify which violet you have: outdoor garden violas and indoor African violets are different plants with different growing needs. Garden species need moisture and good drainage, while African violets are houseplants that prefer bright, indirect light and careful watering. Use the guidance below for the plant you intend to grow rather than treating all violets alike.
Choose the right violet and growing setting
“Violet” can mean an outdoor Viola species or an indoor African violet. Their planting and care instructions are not interchangeable. The outdoor advice below covers heart’s ease (Viola tricolor) and Australian violet (Viola hederacea); local climate and the exact species affect planting dates and overwintering.
| Plant | Setting and light | Soil or compost | Propagation guidance |
|---|---|---|---|
| Heart’s ease (Viola tricolor) | Outdoor; full sun or partial shade, and it tolerates shade | Moist, moderately fertile soil; avoid waterlogging | RHS recommends sowing seed in late winter or early spring; this is UK-based guidance |
| Australian violet (Viola hederacea) | Outdoor; full sun or partial shade | Fertile, humus-rich soil that stays reliably moist but is not waterlogged | RHS recommends seed or division in spring or autumn |
| African violet | Indoor; bright light out of direct sun | Seed compost for sowing; keep it slightly damp rather than saturated | RHS guide describes sowing seed on the surface without covering it |
The RHS profiles do not establish a universal spacing, planting date, or overwintering plan for every violet. Check the needs of the named species and your local climate before setting out outdoor plants. Sources: RHS heart’s ease profile; RHS Australian violet profile.
Plant and grow outdoor garden violets
Heart’s ease (Viola tricolor)
Choose a spot in full sun or partial shade; shade is also tolerated. Plant in moist, moderately fertile soil with drainage, since this species should not sit in waterlogged ground. For seed, the Royal Horticultural Society recommends sowing in late winter or early spring in its UK guidance. Treat that as a regional recommendation, not a calendar that applies everywhere.

Australian violet (Viola hederacea)
This low-growing, spreading or trailing evergreen perennial suits full sun or partial shade. Give it fertile, humus-rich soil that remains reliably moist without becoming waterlogged. The RHS advises propagation by seed or division in spring or autumn. Deadhead to prolong flowering; after flowering, cut back vigorous growth to help keep the plant compact.
Monitor for species-specific problems
The RHS lists possible pests and diseases for these species, but susceptibility does not mean a plant will necessarily be affected. Heart’s ease may be susceptible to slugs, snails, aphids, glasshouse red spider mite, violet gall midge, mildew, leaf spot, virus, and rust. For Australian violet, the RHS lists slugs, snails, glasshouse red spider mite, violet gall midge, powdery mildews, leaf spot, virus, and rust. Identify the pest or disease and assess growing conditions before choosing a response.

Grow African violets indoors
Provide bright, indirect light and steady warmth
The Royal Horticultural Society advises: “African violets need plenty of bright light, but keep them out of direct sun (especially in summer) or filter it with a thin curtain.” Its guide gives a daytime temperature of 18–24°C and a night temperature of 16°C. Avoid cold draughts and sudden temperature changes.
Water without saturating the compost or wetting leaves
Use room-temperature water. Wait until the compost surface is dry before watering, avoid wetting the foliage, and do not leave the plant standing in damp compost. These instructions apply to African violets, not outdoor garden violas.

Sow African-violet seed
- Fill a suitable container with seed compost and moisten it slightly.
- Sow the tiny seeds on the compost surface; do not cover them.
- Keep the container in a lightly shaded spot at 18–24°C.
- Allow three to four weeks for usual germination, as described in the RHS guide.
Troubleshoot a plant that will not flower
Inadequate light is one reason African violets may fail to flower. The RHS also lists cold or dry air and overpotting as possible causes. Check the plant’s light and environment before changing its pot or applying a treatment.
The RHS lists aphids, mealybugs, thrips, and vine weevils as possible pests of African violets, and botrytis and powdery mildew among potential mould or fungal problems. Diagnose what is present rather than assuming a particular symptom has one cause. Source: RHS African-violet growing guide.
