Q: What is this flower and what are the black, bead-type things on the stalk?
A: It is a tiger lily. The black things are called bulbils and can be planted exactly as you would seed.
Lilies, of course, have beautiful flowers which usually produce seeds. Lilies can be cross-bred to produce more interesting flowers that have characteristics of both parents.
These black bulbils, on the other hand, are genetically identical to the parent lily, so they are a good way to get identical plants.
