We have some type of day lily that my grandmother planted forever ago. They have been in the ground almost as long as I have been alive and I am afraid to dig them up. The have survived hurricane Katrina, being mowed down by idiotic lawn care people, trampling by my bother and his children, abuse from contractors...
They have yet to bloom this year though I keep waiting and hoping. I would love to relocate them, but as I said, I'm afraid of damaging the bulbs. The green tops don't die off because we have fairly warm winters.
I recently collected some pods off pink lilies outside an empty house in my mother's neighborhood. I'm hoping I will be able to encourage the seeds to germinate. From what I've read online, some people have had success growing lilies this way and some haven't. It takes a really long time for bulbs to form (learned this from recent garlic attempts), but if I can at least germinate the seeds I think I could get lilies after the first year.
