I gave up on Snow Angel also after reading that it was very temperamental and after it croaked here during its first winter.
This spring I've added:
H. 'Tiramisu'
H. 'Southern Comfort'
H. 'Vulcano'
H. 'Fire Alarm'
In addition to these, the following new ones are on the way:
'Stainless Steel'
'Georgia Plum' ( I have Georgia Peach but don't know this one. Anyone, comments?)
'Electric Lime' This one reminds me of some heucherella that grow here with the colored veining. Does anyone grow this one?
