Hi SusanLee, great to have you join us! Sounds like a pretty nice spreadsheet you made for Julia.
My Snow Angel did absolutely great for about 10 years. All of a sudden this year it looked pretty sad. The one I really have trouble growing here is Christa. It just remains this tiny little plant - doesn't grow, doesn't die. Like Bob, Caramel is happy here. Next spring I want to re-do that area of my garden so plan to move many of them around.
