At least here, Gerber Daisies tend to be more shade tolerant than Zinnias. Also, Zinnias are the easiest plant to grow from seed since they start blooming about 6 weeks from sowing and can be sown directly where you want them to grow. You could pick up a pack of short Zinnia seed for a dollar or two at a local store and have a bunch of plants. They may not be the exact same seed strains but still.
The hummingbirds will love you for the Salvia!
Also, it's easy to root cuttings of Salvias so you can propagate more from your plant and have some ready to bloom in the late summer and fall if you want.
The Heliotrope and Torenia are really pretty too. I love blue!
Looking forward to the photos!
