I bought this plant last year and it came back again. I went back to the nursery where I bought it last year to get more but they weren't sure what it was and didn't have any this year. I call it my face plant. I'm pretty sure it's a cuphea, but not sure about the variety and I have searched and searched online. It's more or less a bush with long thin stems and small leaves. The bloom is small also but lots of them. Any help you can give would be appreciated.
