I think I'm going to move it to a better spot in the garden this year. Maybe it will get going and show me what it can "really" do. Up to this point, I'm not impressed, but I must be fair and give it a better chance before tossing it. It has always been so very short. Even the foliage is short. When I say short, I mean about 12" at best. But it is compromised by the tall Bee Balm that is growing next to it so I'll give it the benefit of a doubt for a couple more years at least.
