Q.Blackberry lilies
In your article on the care of Blackberry Lilies, you state that they begin with planting the bulbs (actually tubers). I have some little “shoots” coming up from my lilies that I would like to share. Can they be dug up and transplanted? What confuses me is that on the same internet page I see blackberry lily seeds advertised. Thanks for someone’s expertise. If the “shoots” can be transplanted, can it be done now?

Blackberry Lily spread through rhizomes and can be divided or shared as you would an Iris plant.
You can harvest seeds from your plants in the fall before they drop from the plant.
Dry and store the seeds in a cool location.
