Polly, absolutely true about Morning Light.
But none of the others that I have are a problem: gracillimus, silberfeil, bluttenwunder, silberfeder, strictus and adagio play together very nicely with my lilies. So do feather reed grass and prairie dropseed. And trimming the tips of any grass that was coming into contact worked beautifully. ML is so gorgeous, I was glad I found a solution. Just wonder why it took so long!
Tracey and Jo Ann, your lilies are spectacular. The colors look so lovely in the light that you have.
