Re: Iris pseudacorus

 

Sean,
 That is a very good point. My stance may be a bit unpopular, but here it goes... I think that SIGNA needs to check out the law, and maybe communicate with the authorities in the states where Iris pseudacorus is illegal to sell, swap, or give away.Â
 Once it is clearly known which plants would be legal and which ones would not be, then no longer give awards to plants that are illegal to grow in those states. The problem is that once escaped into the wild, in a suitable habitat, Iris pseudacorus can crowd everything native out and make an inpenetrable thicket.

Given that a large number of states have banned trade in IrisÂpseudacorusÂand its hybrids and more are likely to follow, I wonder if SIGNA should be having a serious discussion about this. In the last 15 years, two Founders of SIGNA medal winners have been pseudacorus and *five* Randoph-Perry winners have been hybrids. Environmental impacts of invasive species aside, from a practical standpoint it seems odd to be promoting cultivars that are actually illegal for a large percentage of gardeners in the US to grow.
