I've been looking at chick charm Cosmic Candy and believe it's a strong match to S. 'Aross' (Ben Zonneveld, 1982). If anyone spots some chick charms at a nursery, look at back side of the label of Cosmic Candy. I will look to do the same except spring in Massachusetts is much further away.
Also looking for the real cultivar name for c. c. Berry Bomb and Silver Suede.
