Steve I have Symplocarpus foetidus available now bought a few this year to try out as well as the native skunk cabbage both are in one gallon pots and will be bare rooted. I also will have the true Calla which is also hardy here.
Peter I have never seen this form renifolius do you have pictures of this in leaf as well as flower. Also would it be hardy here as well in zone6? THANKS
