No timeline data available yet for this variety.
Sow Rosanne Green Lisianthus 12-13 weeks before your planned transplant date into a 288-cell or other deep-cell seedling container. Light is necessary for germination; cover seeds with only a thin layer of fine vermiculite to control algae while allowing light penetration. Greenhouse production is highly recommended for successful germination and healthy seedling development. Keep the environment warm and humid during this critical phase.
Transplant seedlings outdoors after they have developed several true leaves and nighttime temperatures remain above 50°F. Harden off plants gradually over 7-10 days before moving them into their final location. Plant in well-draining soil rich in organic matter, spacing plants 4 inches apart.
Cut Rosanne Green Lisianthus stems when one or more flowers on the stem are open. This timing ensures the stems are mature enough to last in a vase while the buds continue opening after cutting. Use a sharp knife or pruners to make clean cuts, removing stems in the early morning when they are most hydrated.
