Hi, Australia has tuberous Drosera species. I don't know if many people grow them. But they are quite exciting to see in the wild. South Africa also has some wonderful species that are dormant part of the year. I made a wiki page for Drosera some time ago and added some of the ones we saw in Australia, hoping to get the identity of them correct. Some of them are climbers and some of them grow from rosettes. I added pictures of a South African species, Drosera cistiflora, that I had photographs of even though it isn't technically a bulb. I believe it dies back to thick wiry roots. It has beautiful large often bright colored flowers. http://pacificbulbsociety.org/pbswiki/index.php/… Mary Sue
