What kind of flowers is it alright to use cedar mulch for? I have heard that cedar mulch adds acid to the soil and should not be used with flowers, especially daylilies. Is this so?

The cedar mulch should be fine. However, you should have a soil analysis done beforehand, so you have a general idea of what kind of soil you have. Cedar mulch does acidify the soil some, but slightly acidic soil won't harm most plants. If you're worried about the acidifying effect, add some limestone to the mix, or sprinkle some on top of the mulch.
