I picked up an interesting intergenus hybrid yesterday and would like to find more. The one I bought was H. paramutabilis x H. syriacus and is a triploid. I'm looking for one of the ones McFadden has created and that are suppose to hit the commercial market soon. Are any of the H. rosa-sinensis x H. paramutabilis available yet?
Aside from the many H. moscheutos group of hybrids, are there any other intergenus hybrids that are available to the public?
