Violets are all members of the viola family, which includes about 500 species of annuals and perennials, which are mostly small, mounded shrubs.
All types of violets have five-petalled flowers, and mostly flower in white, yellow and purple, though other colours are available.
Pansies are also in the viola family and were developed when the small-flowered heartsease (Viola tricolor) was crossed with other species.
Sweet violet (Viola odorata): a perennial that spreads by runners, grown for its highly scented flowers, which can be single or double, appearing in spring and early summer. Can be weedy in ideal conditions, and grows to about 20cm tall.
Viola hybrids: known as pansy and viola, these small annuals are neat plants with flowers that range from 0.5–8cm wide in a variety of colours, many with bi-coloured decorative patterns and “whiskers”. Usually purchased as seedlings or potted colour to flower in winter and spring, they grow to about 15cm tall and wide.
Native violet (Viola hederacea): Australian creeping perennial with circular leaves and small lavender or white flowers with darker centres, appearing mostly in the warmer months. Prefers shade and grows to about 10cm tall.
Johnny Jump-up (Viola tricolor): flowering in spring, this violet is treated as an annual and self-seeds before dying. It has small, bi-coloured pansy flowers with face-like patterns, and is about 10–15cm tall.
Violets are perfect for cottage gardens and fragrance gardens. The annual varieties are used as bedding colour and pot specimens.
1. Choose a sunny or shady area.
2. Improve soil with generous quantities of compost or soil improver.
3. Delicately plant your violets.
4. Keep moist but not wet, watering once or twice a week during dry periods.
5. Apply fertiliser when planting, and once a month thereafter.
Violets make excellent pot specimens, especially the annual varieties, which are sold as violas. They are also good clumping plants in garden beds, where they should be planted into free-draining soil improved with compost.
Violets do not need pruning, and mostly flower in spring or early summer.
Protect seedlings from slugs and snails by using snail baits or beer traps. Hose aphids off with a strong blast of water or use a pyrethrum spray, and check plants for caterpillars, which eat the flowers and leaves. Squash them or apply a caterpillar spray such as Dipel or Yates Success.
Nemesia: annual or short-lived perennial bedding plants, some mildly scented, which are good for borders, rockeries and pots in full sun to part shade.
Primula: a spring-flowering primrose, sold as an annual or perennial, which prefers moist soil and dappled shade.
Winter rose (helleborus): low-growing perennial plants with simple five-petalled flowers in mid-winter to spring.
