Lisianthus - Eustoma grandiflorum "Rosanne 1 Black Pearl"

NEW! Season 2026

Group 1

Lisianthus Rosanne series is often characterized by its unique, special colors. The full, double flowers top its strong stems with good vase life.

Sow indoors about 12-13 weeks before planting out and the risk of frost is over.
Light-germinating, can be covered lightly with Vermiculite to maintain a more even humidity.
Keep the seedbed moderately moist, not too wet but not too dry.

Lisianthus thrives in warm conditions (cooler during plant growth), therefore it is recommended to grow them in greenhouses. They like well-drained soil with lots of organic matter.
A challenge to sow, as they take time, so be patient!

Be gentle with their delicate roots when transplanting and make sure they do not become root-bound.
The plants need support, such as a net support.

Harvest when one or more of the flowers on a stem have started to open.

Please note that our seed bags are delivered in Swedish!
