1. Morphological characteristics
Viola is a biennial or perennial herbaceous plant. The plant height of viola is 20~40cm, the whole plant is covered with gray felt-like pubescence; leaves are alternate, obovate, and blue-gray in color. Viola flowers are densely arranged on the peduncle, with 4 petals, flower diameter of 2cm, in white, purple, red, and other colors, also bicolor, with a faint fragrance. The fruit of viola is club-shaped, the seeds have white membranous wings, and the flowering period varies by variety.
2. Growth habits
Viola prefers to grow in an environment with suitable temperature and good ventilation and can tolerate short periods of -5℃ low temperature. The optimal daytime growth temperature for viola is 15~18℃, and the optimal nighttime growth temperature is around 10℃. Viola has low requirements for soil. When planted in loose, fertile, well-drained, and deep-layered potting soil, viola flowers will be more beautiful.
3. Cultivation and care
Viola should avoid direct sunlight and is suitable for indoor potted plants with sufficient scattered light. It is best to avoid high-temperature and high-humidity environments. Viola should not be watered too much, as it can easily cause root rot. During the growth and development period, apply a dilute decomposed liquid fertilizer or compound chemical fertilizer once every 7~10 days. Do not apply too much nitrogen fertilizer, otherwise, the leaves will grow very lush with few flowers. The ratio of nitrogen, phosphorus, and potassium should be 1:1:1.
4. Propagation methods
Viola mainly propagates through sowing seedlings, and it can also adopt methods of cutting propagation or division. Since viola has a straight root system and underdeveloped lateral roots, seedlings should be transplanted before the true leaves unfold to minimize damage to the root system. If移植ing too late, the root system will be longer, making the operation difficult.
