This is the best year so far for this approx 5 year old Weigela. I bought it during a trip to Schreiner's Iris Farm. Their's were huge. I imagine those are descended from an old cultivar from the midwest, although I can't know that for certain.
In my yard, deer are a major challenge. They did nibble tender growth from thus young Weigela, but leave it alone now. I think it's not tasty for them.
This year, it's covered with masses of flowers. Quite nice.
