This is certainly true, but does California have any  bulbous plants that 
emerge in earliest spring - the equivalent of Crocus or early Narcissus 
(etc, etc) in the Mediterranean? I do not mean high altitude snow-melt 
plants (I've seen Erythronium purpurascens emerging in best 
Soldanelloid-fashion from melting snow in July). I know that there are no 
autumnal-flowering bulbs in California, but in my experience most bulbs, 
even in southern California, flower comparatively later than many of their 
counterparts in the Mediterranean, with the main flowerng of winter annuals 
rather than before them. I have not really botanised in California in 
January and February, but neither can I recall any really early bulbous 
plants from cultivation or literature.
