Expert tips
The key tip
Sweet violet thrives in moist, rich soil and partial shade. It self-seeds generously if happy.
The common mistake
Planting it in full scorching sun and dry soil: it becomes weak and barely flowers.
The pro's trick
Plant in dense clusters: they create a moister microclimate and flower much better together.
Care
Watering
Keep the soil constantly moist but not waterlogged, especially during flowering and growth periods. In winter, reduce watering without letting the substrate dry out completely. Regular watering promotes generous and prolonged flowering.
Light Exposure
Place your sweet violet in partial shade or filtered light. It tolerates morning and late afternoon sun, but appreciates protection from intense midday rays. Shaded exposure suits it particularly well in warm climates.
Pruning and Cleanup
Regularly remove spent flowers to stimulate the formation of new buds. Eliminate dead or diseased leaves as they appear. Light pruning after flowering encourages a compact and regular shape.
Soil and Potting Mix
Use a rich organic mix composed of potting soil, compost, and peat or coconut fiber. Good drainage is essential to prevent root rot. Adding sand or perlite improves substrate aeration.
Fertilizing
Apply a balanced diluted fertilizer every three weeks during the growth and flowering period (February to May). Reduce or stop fertilizing in summer and autumn. Over-rich fertilizer promotes foliage at the expense of flowers.
Diseases and Pests
Watch for powdery mildew in cases of excessive humidity combined with poor ventilation. Aphids can infest young shoots in warm weather. Ensure good air circulation and remove damaged leaves to prevent fungal problems.
Did you know?
The sweet violet was already cultivated by the ancient Greeks and was laden with symbolism: it represented modesty and faithfulness. Napoleon adopted it as his personal emblem after his exile to the Island of Elba, which is why his loyal supporters were nicknamed the 'Violets'. Its delicately scented and edible flowers long inspired perfumers and pastry chefs.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
