Viola Odorata is one of the few flowers that has early spring flowering. It also flowers again in August to October. Its very attractive to butterflies and other pollinators, and often used for erosion control.

Plant indoors in the late winter. Or, start directly outdoors after danger of frost has passed, or in the late summer and fall.

Plant in partial to full shade in rich, moist, well-drained soil.

• You have two options for planting seeds: Sow them directly into the garden at a depth of 1/8 inch after the risk of frost has passed, or in the late summer and fall. Alternatively, start seeds indoors in the late winter.
• Cold stratify seeds by mixing them with peat moss, placing in a ziplock bag, and putting the bag in the refrigerator for 6 weeks prior to planting. Plant 4 - 5 seeds per cell or plant.
• Once seedlings sprout, ensure they receive plenty of light by placing them on a sunny windowsill or positioning them 3-4 inches below fluorescent plant lights that are switched on for 16 hours daily and off for 8 hours at night. Adjust the lights as the plants grow taller. Avoid using incandescent bulbs as they generate excessive heat. Remember, most plants need a period of darkness to thrive, so do not keep the lights on for 24 hours.
• Transplant into garden when temperatures are consistently warm or in the late summer and fall.
• Before transplanting seedlings into the garden, it's essential to "harden them off". This involves acclimating young plants to outdoor conditions by placing them in a sheltered outdoor area for about a week. Initially, shield them from strong winds and direct sunlight. If there's a risk of frost overnight, either cover the plants or bring them indoors, then return them outside in the morning. This hardening off method helps strengthen the plant's cell structure, minimizing transplant shock and sun damage.
• Space plants 8 inches apart in garden.

• Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
• Mulches play a vital role in preserving soil moisture and ensuring consistent soil temperatures. When it comes to annuals, using organic mulch made from shredded leaves not only enhances the appearance of the bed but also enriches the soil as it decomposes over time. Remember to keep mulch away from the plant stems to avoid potential rot issues.
• Keep plants fairly moist by watering once a week with about 1 inch of water. Keep an eye on the plants during dry spells or drought, and water more as needed. Check this by pressing your finger into the soil to about 2", if it is dry, water is needed.
• Deadhead any spent flowers to encourage further blooming. Cut back foliage if bushier plants are wanted.
