My Mexican Flame Vine is starting to really bloom lately. It's a butterfly-attracting vine that looks like a an orange daisy. It loves hot weather and can be quite vigorous if given the right conditions. It's somewhat hard to find, but worth searching for. It will come back in zone 8 if given enough protection. Otherwise, it can be grown as an annual. I think it would be a good hanging basket plant since it would cascade out nicely. I think it could also be a nice ground cover, though I've found that slugs like it. In order for it to climb well, you have to either tie it or twine it onto a trellis or fence. I've heard that it's pretty easy to grow from seed, so I will be saving some seed from mine this year.
