Now that the growing season is over in Minnesota, I'm starting to plan for next year. My whole yard is pretty shady, and I mostly grow perennials for foliage. I miss flowers! I'm thinking of starting a new perennial bed in the sunniest corner (a triangle about 12 feet on each side). It's still not full sun - it gets dappled light through the day, and some direct sun mid-afternoon. It's enough that the sedum spectabile grown nearby do well, but mums and asters (even well pinched) are gangly.
What are your longest blooming, most showy light shade flowering plants? Which do you like best?
I'm also going to post this in the perennial forum.
