Hi Scott. Ya, that BVt hybrid (and it's sister seedling, named Rh. 'Sandra Hinton') are the absolute best Rhodos I have. The BVT (Brachycarpum var. tigerstedtii) parent also does well, but isn't as showy. I haven't propogated mine yet, but I know that it has been passed around a bit. If you want to try some cuttings at some point (they're taken in the fall and can be very tricky), just let me know.
Here's Rh. Sandra Hinton (same cross, grown from the same seed lot), which is maybe a little less impressive than it's sibling. Must have a nicer flower or something for it to be the named plant. Who knows? :
A blurry one from fall showing the bright white undersides of the leaves:
And the BVT itself, the first is from fall, but it looks the same now, second picture. It's a more open plant, more like a small tree. Not the best Rhododendron, but worthwhile nonetheless:
That opaca is a survivor, however I have a feeling that only the leader (which is mostly brown) was above the snow line when we hit -30C!
