Hi John: Thanks for the information. I'll check the reference you cited when I get home tonight. Always on the lookout for more geophytes with summer growth cycles (or that might be switched around into a summer growth cycle) that might burrow deeply enough into the soil to be hardy here.

Many can be grown in USDA Zone 9, with just a little protection, but most, if not all, will not stand frost and temperatures at night in the 40 F range are needed. Thus it should be possible for those who can provide some protection, to grow them. They are, in my opinion, quite beautiful and it is interesting to think about crossing some, especially the yellow species, with Pelargonium zonale or with Ivy Leaf species. The question of hardiness has not, to my knowledge, been factually established. I would not be surprised at all to find them hardier than supposed, but I would not think they would ever be hardier than, (or less hardy) than our common window box cultivars, which have survived many winters for me in San Francisco.
