Kevin asked about nonflowering Narcissus cantabricus. Perhaps they need more fertilizer, or a different kind. A dry summer rest is appropriate for this species, but they should not become desiccated, and in Los Angeles that might be happening even if the pots are in the shade. In nature they tend to grow in rocky ground where the bulbs are protected from excessive drying. Kevin, try covering your pots with rounds of styrofoam, that might help. Also, how often do you repot them? They should be lifted at least every second year and put in fresh gritty soil. It's normal for the leaves to emerge in late fall. Depending on the subspecies, flowers will appear any time from November to February. My first one opened a couple of days ago. I grow them in a plunge frame in full sun, but it is much cooler here in summer than in southern California. Jane McGary Northwestern Oregon, USA
