Growing Tips
Lisianthus rewards an early start and steady, gentle care.
- Start seeds early because lisianthus develops slowly from seed.
- Surface sow the tiny seeds and avoid covering them deeply.
- Provide bright light and consistent moisture during germination.
- Give mature plants good airflow to support strong, upright stems.
Seed Storage
Store unused seeds in a cool, dry, dark location. Keep them sealed in an airtight container away from moisture, heat, and direct sunlight. Because lisianthus seeds are very small, handle packets carefully to avoid losing seed.
Important Growing Note
Lisianthus is known for being relatively slow to grow from seed. The tiny seeds are generally surface sown because they require light for germination. Light green flower color can vary among seed-grown plants, and seed-grown flowers may differ in shade, form, and petal arrangement from the parent plant.
