I have had my Peace Lily for many years. It spends is winters indoors but most of the time out is in bright shade outside Zone 9a. It hasn't flowered often for me. But maybe it being outside, i just miss the bloom? As you can see, it's fairly large with lots of babies under the mother plant. And it is healthy and gets fertilizer 3 times a year. I'll take giant and healthy over flowers. But Ihope it flowers again some day and I see it.
