Try posting this on the perennials forum. These are not true lilies, plus there's more visitors on that forum so you're more likely to get a response.

The Iris forum would also be a good place, since blackberry "lilies" are actually a member of the Iris family.

Your "bee-bees" are seeds, and should sprout. I would hold them in the frig or in a cool part of the house until you are ready to plant them next spring, whenever that is for you. Use a paper envelope, as these sees hold a lot of moisture. Unless they are dried sufficiently, they will mold in a plastic bag.

Hi - A big thank you for all the advice.
I just learned that they will sprout and grow.
So, I will hold them til next spring.
Thanks - tina_2
