I've tried several species of South African Crinum from seed here in Phoenix, Arizona.
They don't need to be sitting in water. They grow just fine with regular watering. I
have read there are aquatic species but I don't think most of us are growing those.

They won't bloom in containers. They reach a certain size and stop growing.

The hybrid Ellen Bosanquet survives in my garden - and is evergreen - on rain alone. We
average 8 inches annually, summer and winter. Our spring is extremely hot and dry
without rain for 3 months or more. It will not bloom unless I give it extra water, in
which case it blooms well. I am not worried about it invading the desert, though it is

Hymenocallis I can't even keep alive unless they are standing in water. In the warm
water of my pond they burst the pot every year or so, and bloom reliably. If I had known
puppies would chew them I would have three kinds instead of one. If any of you got the
seed of H. sonorense I sent to the seed bank a while back, please try and set some seed
to send to Dell - this is a plant my puppies killed.
