Um, yep, I considered rushing out to dig up the Fulva but then had another think. I know at this point which is which, that is, which lily plants are Fulva and which are my new unnamed-but-groovy acquisitions. Unless the Fulva multiply over the winter (GAH!
) I'll still know in the spring which is which. If I watch them closely and make sure to remove new starts and thin the Fulva during the season, I think I'll be okay. For a while.
(though I can hear them plotting now, underground, how to foil my plans to contain the Orange Flood!)
