We don't know much about this one, but we do know a little bit about Greg Johnson. He's been hybridizing for a decade or so but has released very few plants. The reason why is that he perhaps the most thorough at evaluating them of any hybridizer. He will not release a plant until he is sure about it and he doesn't decide that lightly. A man of remarkable patience. Possibly an H.'Invincible' hybrid. Very Rare to date......
Hybrid of 'Spritzer' X H. pycnophylla from Greg Johnson of Marshalltown, Iowa; impressive gold foliage in a moderately dense mound.
