I got some in a trade. I didn't know how tall they would really be, and ended up putting them behind some shrubs and other perennials where they can barely be seen. All summer I meant to move them, but it was too hard to get in there, without damaging lilies, etc. Now it's all died back a bit, so I could clamber in there without wrecking things.

But is it too late to move them? Thanks!
