Dear Andrew and all, Thanks for the views of your bulbous Pelargoniums. That got me to the PBS wiki to see that there are quite a few species represented there: http://pacificbulbsociety.org/pbswiki/index.php/… and I was shocked to see no bulbous, hardy Geranium such as G. tuberosum or G linearilobum. I grow both and find them modest, but reliable species here in my hard climate. The latter is far less common, but I notice it is available in 2 forms from our friends Odyssey bulbs (http://www.odysseybulbs.com/iristomoraea.html). Does anyone else grow these or other species of tuberous Geranium? Need to get a new wiki page and post some pix. Thanks Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
