Greenfield, That is going to look great when it fills in.
I bought this wreath (on sale) already planted and then put an extra plant in the middle on a cement leaf. I don't have enough sun exposure and place for plants indoors so it didn't winter over in the house very well, so not sure if I will create my own from the wreath form or get a new wreath
I find the semperviums a bit expensive to buy individually, so for $20 a preplanted wreath works better for me
