NOTE: If you ship LA you have to pack them with water around their roots. They can't dry out like the bearded.
Yes, they like lots of water but can be grown without water features. If your soil dries out quickly then the pan idea of Arlyn's would be a help. Keep them mulched and wet and they should be happy.
Another NOTE: Most LA vendors now have varieties that grow better in colder climates, which might be the way to go in Iowa!
