From where it is planted which is far too close to a big Weigela and not at all where we would put it, we are guessing that it is one of the few plants that were here when we moved in. Having said that, we ought to have seen it flower last August, but it did not. No, neither of us remember buying any Caryopteris and it is not on the list of plants we make when we do go buying things.
