It’s a European wildflower that several states now classify as invasive, so you have to contact the local extension agency before you plant it to avoid fines.

9. Bells of Ireland (Moluccella laevis)

You should fertilize them twice per year with a slow-release fertilizer, once during the spring at the beginning of the growing season and once during the late summer. If you regularly deadhead the plant, new blooms will appear.
