I finally broke down and bought 2 c.m. at Lowe's on clearance late last year. Then we got the coldest winter on record. In the spring, they were dead twigs in the ground *shrug, oh well*. Then later, I'm spraying weeds and spray what I think is a poke weed and then realize: Its the C.M. Washed it off and they are both growing and doing very nicely. These must be newer very cold hardy varieties to take our winters. Don't know what color they will be.
