| I have seen very well behaved varieties and of course there are the incredibly invasive varieties. These pictures look a lot like the variety I had. I planted 4 of these from 3" pots about 3 years ago. I needed to remove them this year for an irrigation system. After 4 weeks of repeated applications of glyphosate, I ended up having to dig them out of the ground. The roots were 2-3 feet deep. It's an incredibly tough plant. More like a very hardy shrub that grows anew each year than a typical perrenial. It was a pretty plant when they were young then they were a huge nuissance. I was constantly pruning to keep them under control. I would not recommend them unless you want them to take over a fairly large portion of your yard. Aaron |
