Cardamine

Common Name(s):

Description

Bittercresses (Cardamine spp.), in the Brassicaceae (mustard) family, are the common cool-season weeds, but can persist and spread year round in shaded, moist environments.  Plants form a basal rosette of leaves. Flowers are white and form small, cigar-shaped fruit. Plants are prolific seed producers and seeds are forcefully expelled 3 to 6 feet. Freshly-shed seed have no dormancy. 

Wildlife Value:  Members of the genus Cardamine support the following specialized bee: Andrena (Scaphandrena) arabis.

Insects, Diseases, and Other Plant Problems: Plants often harbor whitefly and mites and have been implicated as alternative hosts for some diseases. Seedlings are numerous, small, and are time-consuming to hand remove.  Do not let plants go to seed. Manage bittercress populations around the property to prevent spread. Inspect all new plant materials for infestations of this weed. Bittercress is well managed by available preemergence herbicides but due to its prolific seed production and continuous germination it continues to be a challenging weed. 

 

Season: winter annual weed

Propagation: Dehiscent seed pod
