What flowers did the woman purchase?

M Hello, Greenleaf Nursery, this is John. How may I help you?
W Hi, John. My name is Martha Sweet, I bought some lilies from you last Saturday. I water them everyday, but it looks like they’re dying.
M Hmm. Too much water can be a problem. Try putting the lilies in indirect sunlight and don’t water them everyday. If they don’t get better in a week, bring them back and we’ll have a look at them.
W OK. I’ll give it a try. Thank you for your help.
