Andrea B. Posted February 24, 2013 Share Posted February 24, 2013 Blum, A.G. (2013) Campanula rapunculoides L. (Campanulaceae) Creeping Bellflower.

OpizDrymocodon rapunculoides (L.) Fourr.Rapunculus redivivus E.H.L.KrauseComment:I was disappointed to learn that the lovely C. rapunculoides has become rather invasive after its introduction to the US. I can't say I'm surprised, however, because this Creeping Bellflower seems very tough. I've found them growing in the sidewalk cracks in Northeast Harbor (ME). The NEWFS entry(1) charmingly observes that "it is edible, so escaped individuals can be permanently disposed of".Like most Campanula, this specimen exhibits UV-dark anthers and stigma and a UV-bright corolla. It has visibly fluorescent anthers and nectary under UV stimulation. Reference:1. New England Wild Flower Society (2013) Campanula rapunculoides.
