I am not sure someone's mentioned these already
larkspur (Consolida not Delphinium)
Lychnis/Silene coronaria
Euphorbia marginata
Digitalis
Campanula persicifolia
Campanula medium
Poppies
Adenophora (don't know which one, but it's very invasive around here, both in seeds and roots!)
Echinacea (coneflower)
Salvia (wild, purple flowers)
Linaria purpurea
These are the ones I can tell I felt sorry for planting in my garden !!!
