Oh, sure. I guess pretty much any flowering plant that grows well in the area I like to some degree. OK, now you've sold me on mums, LOL. Is spring the best time to plant them?
Here's a pic of my garden. In May, June and July, I love it. In August there's not much, and September is just dead. I know it's pretty full, but I can remove things for some later bloomers.
Another plant that used to be a late summer bloomed for me is Eupatorium, and I love it, but now it's mid summer.
