I have Bloomeria crocea, grown from seed of a population in the coastal 
hills between Monterey and Salinas, in my rock garden where it has survived 
5 F for a lot longer than an hour or two (I live in the same region as Ken 
but at a higher elevation). I was surprised by its persistence. The plants 
on the rock garden flower a week or so later than those in the bulb frame, 
which are much more robust, I must admit. For comparison, Alstroemeria 
psittacina, which Ken mentioned as invasive in his garden, does not survive 
the winters here. Dichelostemma congestum and Triteleia hyacinthina both 
grow well in the open garden in a well-drained border, as do several other 
Triteleia species. I am gradually adding species to the garden as I get a 
surplus in the frame collection.
