Crested Water Lettuce is a different form and more attractive than the regular water lettuce. These float on top of the water in koi ponds. They die out in the winter in temperate climates but can be maintained in a sunny window in a water bowl. These are not collected from the wild as they do not occur there. Not shipped to AL, CA, Fl., La. Ms, TX, SC.and WI. Not sure what the reasoning is for Wisconsin????
