Thanks much for your input! The two spp. at O. sternorrhyncha and O. purpurea possibly 'Garnet.' The latter has purple leaves that lay flat on the ground with a pink flower. I am still wondering how mature bulbs can be killed effectively. I have always been an organic gardener, have never applied toxic chemicals and that is why I asked the solarization question (I've solarized before). I'd consider a chemical if I could be sure the mature bulbs would not survive but would prefer another method. There are hundreds of bulbs in that bed and I have dug up many in the past but now there are too many.....especially tiny ones. Thanks again for your help, Pamela _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/…
