Last Saturday I dug up a pot of Calochortus vestae to repot them for this coming growing season. I was surprised to see that the largest bulbs were beginning to put out roots. They had been outside all summer with no water since the rains stooped last March. I have wandered how do they know it's time to break dormancy. Do they have an internal clock, is it temperature changes, daylight length (how that would work I don't know as they have 3 inches of soil over them?). Sunset zone 14.
