Very pretty in flower, Caroline!
We enjoy growing (and eating) horseradish. Just like Deb said, something loves to eat the leaves, which surprised me in the beginning because I didn't think it would have many pests. But, I think there are several pests, one is a beetle that makes lace out of the leaves. We sprayed with soapy water to try to get rid of them... I think they are under control now (kinda).
In spite of pests, we like growing this plant and have-not found it to be aggressive here the northeast part of Texas.
