Too late for this season around here. Can you grow crocuses where you are? What season do you generally see them there? I always thought they needed a winter of chilling before they would sprout, which is why they're fall-planted and spring-growing bulbs here. Perhaps they need refrigeration for a period of weeks in LA, then can be planted. I'd check with a local nursery, or maybe some kind Southern DISer can chime in here.
And yes, they grow very well in pots as forced bulbs. Pot them up, chill for 6 weeks, then pull them out, put in the sun, and voila! Croakies!
