Notes. Colonises degraded sites. May hybridise with Fumaria muralis. Can be difficult to control due to a strongly persistent soil seed bank. Herbicide control can be unpredictable and variable, with tolerance and resistance varying among species of Fumaria. Potential biological control agents were assessed after one species Fumaria densiflora developed populations with herbicide resistance.
