They are a nice plant to have around. Hardy and prolific. I fertilized some of ours and they almost seemed to dislike it:) So I haven't touched them since. This photo is a Day Lilly. The Day Lilly is a bed of long leaves, maybe up to 2 feet. Then there are tall stalks with a cluster of flowers on the end. The Tiger Lilly has no bed of leaves, just a tall stalk, maybe 4-6 feet with short leaves all the way up it. Then again a cluster of flowers on the end. I agree with you Lillys are a beautiful flowers.
