FAQ
Are these seeds pelleted?
Yes. This listing is for 20 pelleted seeds, coated with harmless clay to make the naturally tiny lisianthus seed easier to see and sow.
When should I start Black Pearl Roseanne Lisianthus?
Start indoors 12-16 weeks before the last expected frost. Lisianthus grows slowly at first and needs early, careful indoor sowing for strong summer stems.
How dark are the flowers?
The blooms are deepest purple and can appear nearly black, especially in lower light or when paired with pale flowers and silver foliage.
Is lisianthus the same as a rose?
No. Lisianthus can look rose-like in arrangements, but it is Eustoma grandiflorum, with smooth cut-flower stems, oval buds, and blue-green foliage rather than thorny rose canes.
