I have had lilies, I believe Oriental, in my garden for a few years. For some reason this year on the top of two of my plants they almost look like they grew a whole new littler plant. These two did not really flower very well with multiple blooms as usual.

Did I do something wrong? Did they possibly get cut back too early and this happened? If I remember right I basically just cleared the brown leaves this past spring as I cleaned up my garden, but it is possible that another member of my family cut them down late fall of last year.

What can I do so this does not happen again? Should I maybe be dividing them? I just have never seen this before.

Thanks for helping
