HOW TO GROW:

Lisianthus is best started indoors (recommended) and is known for being a challenging but rewarding flower to grow from seed. Begin sowing 12–13 weeks before your last frost date into 288-cell trays or other deep-cell seedling containers to support its long taproot. Greenhouse or controlled indoor conditions are strongly recommended, as lisianthus requires consistent warmth, humidity, and light to germinate successfully. Seeds need light to germinate, so do not cover them with soil—instead, a very thin layer of fine vermiculite can be applied to help retain moisture and suppress algae. Germination can be slow and erratic, often taking 10–20 days or longer. Maintain bottom heat and high humidity, and be patient—lisianthus seedlings are slow-growing at first. Transplant outdoors after danger of frost has passed, into full sun and well-drained soil.
