I could quite see Blyth and Burseen as perferred hybridizers for me, but I have to agree with Debra that it will depend a bit on what ends up doing well for me here. I can say that the Burseen rhizomes I got this year (quite a few!) are a hardy breed.
On a worried note: we have had rain and rain and more rain. The long slow, ground saturating type, so I hope rot does not set in. I have had to add topsoil to a few washouts as well. The survivors will get gold stars from me!
