I remember trading you one of the plugs. There is the possibility that it has been mislabeled. I looked on the internet for other pics of S. 'Lime Frost', only to find one on the North Hills Nursery website. Here are the pics of my 3 different plantings. The only one that is taking on a growth pattern of a heuff is the last one pictured that is growing in a strawberry pot. We will have to investigate this!!
