This is a bed where I want a fresh start. I'm looking for suggestions on Perennials that will give me attractive color from Spring to Fall and be low maintenance. The bed is in full sun til late afternoon. I'd also like your thoughts on the number based on your recommended spacing in this 7 1/2 foot bed. Obviously, I want something that will do well in Zone 5.

I was going to rummage through the clearance tables at Lowe's but decided that would be penny-wise and pound-foolish. So, I'm making this post to get some creative ideas from you experts.

Thanks a lot,
