I have testament to how truly hardy a purp really is.
It all started with a death box purp from Lowe's. I took it home, replanted it in a pot and left it be for several years. It thrived without much of my intervention. Then one day about a month ago, my dog dug it up, and I thought it was gone for good. Several days later, I found its rhizome, with badly chewed off pitchers, looking alive still. So, I re-potted it and now its putting out new pitchers!! Truly a hardy plant indeed!
