Lynn that looks really pretty. I thought this sedum's leaves were bigger. But I know it was a plug because the plug was obvious from the shape of the root ball. I guess they had to put it in a bigger pot since they state on their site pot size of the plants. It is like telling people they are getting a gallon size plant when it is a gallon of soil but a plug root ball.
I planted some lilies with sedum as ground cover in my patio pots last year. I am starting to like the look. I am getting the hang of this perennial pots for the patio. It was getting expensive and a lot of work looking for the right annuals.
I will take a pick when the lilies bloom. I hope you post pics too when the lilies bloom.
