What perennials co-exist well with roses? Do lilys work?

Question:I'm trying to fill in space between my existing roses until I can afford to get new ones.

Answers:
I've planted colombine and daisies with my roses and have had good luck. The colombine is done blooming for the year but the daisies are just coming out. I have had lillies planted close to my roses with no problems but I transplanted them. Good luck.
