I suppose there is room for debate to consider Rhexia virginica as a geophyte worthy of PBS discussion. However, for the first time ever I have it blooming in my garden and I am so excited that I had to share my photos: http://badbear.com/dkramb/webpix/… http://badbear.com/dkramb/webpix/… Two companion plants can barely be discerned in the second photo include Sarracenia flava (lower left) and Iris tridentata (right). I investigated the root structure on Google and it led me to this link: http://www.phytoneuron.net/PhytoN-Rhexia.pdf which has a wonderful line drawing on the top of Page 5, which bolstered my confidence to post this message without an "OT:" prefix (even though elsewhere in the article it declares Rhexia has fibrous root structures). There are lovely color photos of Rhexia species on page 7. :-) I acquired Rhexia lutea the same time as Rhexia virginica, but it died after I tortured it for several months. Enjoy!
