I've had white rain lilies (that I dug out of the roadside) that bloomed both in the spring with the rains and again in fall (rainy season). They naturalize readily here just like the red lycoris radiata. I don't have many now; I guess voles got them. I've never really seen them, but I seen suspicious holes every once in a while, like yesterday. I'm going to fill it with rocks to see if there is any activity. I recently received some white rain lilies as extras in a trade, which I will plant with grit, pepper and garlic. Wish me well in successfully getting blooms with the voles and squirrels around.
