Hi Weedwhacker, I just love day lilies & do have a couple of big clumps on the hill. I think that's a good choice, too, as they multiply & will eventually cover a lot of area. I dug out a 6ft. wide, free-form half circle flower bed on the hill when I was able to work out there all day & keep it perfect. I've thought about just putting the whole slope back to lawn but lawn is just so boring. Thanks for reminding me of an option I also love.
