Non-native plant
"I ordered a variety of wildflower seeds for a patch. I naively assumed American Meadows would sell native seeds, or at least indicate seeds are non-native. While this isn't a banned invasive species like the Dame's Rocket they also sell, it is not a native plant so not a good fit for growing native wildflower patches. It is very pretty and came in well in the second year. It's not overwhelming other plants. I probably won't pull them as I have been with the Dame's Rocket."
