Hi Susan
You'll love the Asarina, they're delightful! Hummers enjoy them too.
Most of my garden is composed of perennials but I do enjoy annuals in containers on the deck and around the entrances. My current favorite is dragon wing types of begonias.
For the garden I gravitate toward old fashioned, re-seeding annuals that have a cottage garden appeal to my eye. Larkspur and Shirley Poppies are my favorites, but I also love cleome, nigella, four of clock, and balsam.
