Another carpet type flower that slowly expands is Dianthus. I've had this one for quite a few years and it requires some cutting back every year now.
The next photo is Amsonia. It is a nice clump and seems to like it's location near some Lambs Ear.
I always find a spot for flowering shrubs on standards so when I found both a Cotoneaster and Gardenia in the 50% discount bin at a local nursery the price was right. After being in the ground for only a month the Cotoneaster bloomed.
