  • Question

    I sent you pictures a few days ago of a plant I now think is an invasive garden plant, Spiraea japonica, Japanese spirea, which you have in your key, but which I didn't see because I didn't think to check the plants listed under "Woody Plants." I should always check "Woody Plants," even if the plant doesn't seem at all woody to me.

    Answer

    Dear Davidreik@comcast.net, species of Spiraea are woody, though sometimes the young plants may not seem it except near the base where there will be wood and bark. Best wishes.
