My plants are growing and spreading but it is April 1 and no flowers yet. When should I expect blooms? I live in San Diego and the plants were planted as seeds in the fall and are now almost 4 feet tall.

There are a few reasons they might not be flowering. The most likely cause is too little light - ideally they should be getting 16 hours per day. There's also a decent chance that they're getting too much nitrogen and not enough phosphorous.
