Fasciation. Sometimes caused by a virus or chemical spray. Some are random mutations and are propagated. Here's a fasciated Cryptomeria in my garden. It is also known as a 'Cockscomb Cryptomeria. I have some sedums that are also fasciated.

thank-you botann!Your information was very helpful.I posted a picture of the lily as it is now,and I will post another after it blooms.I also have sedum in the same bed,perhaps they will be different this year as well.I am hoping the lily stays healthy,and returns next year-it is one of my favorites.Linda
