Violas are an early blooming plant. These perennials are often grown as an annual. Most people believe they are annuals. They are early bloomers in late spring to early summer. Then, shrivel in the mid summer heat.
They are native to the southern hemisphere. Easy to grow, you will often find Violas growing in the wild, in their native regions.
Small plants produce a wealth of dainty, clear-faced, fragrant blooms in jewel-like shades; yellow, apricot, blue, scarlet, white and violet. Viola is generally more winter-hardy than the larger-flowered pansy.
Viola are popular, easy, and fun to grow. Fill an area or entire bed with Viola for a striking spring effect! They also are great in windowsills and containers.
Growing Conditions and General Care
Viola plants prefer cool to warm climates, and wilt a bit in mid-summer heat. In warmer areas, we recommend partial shade. They tolerate a variety of soils. Add a general purpose fertilizer when planting them, then once a month after that.
Once your Viola plants are established, they should grow well, even if left unattended. Soil should be moist, but not wet. Water them during dry periods, once or twice per week. Keep them well weeded.
Remove spent blooms to promote additional blooms, and extend the blooming period. This will also keep the appearance neat and beautiful.
Violas are grown from seeds. They like full to partial sun. Viola can be directly seeded into your flower garden or seeded indoors for transplanting later. For spring blooms, you need to start your Viola in pots and containers indoors six to eight weeks before the last frost.
Sow Viola seeds early in the season and cover lightly with 0.8 inch (2 cm) soil. Water thoroughly once. They germinate slowly.
Transplant Viola seedlings into your garden after the last frost date for your area. Space them 6 inches (15 cm) apart. They will tolerate a little crowding. If you are creating a flower bed, you may want to create a pattern or color scheme prior to planting. Or, use mixed varieties.
Pests and Disease
Viola seldom have problems with pests and disease. If pests or disease problems occur, treat early with organic or chemical insect repellents and fungicide.
