Tree-like bush in dappled shade of maple
I'm looking for advice on a specimen flowering bush or small tree to plant in the dappled shade of a maple tree. Ideal height is 8-12 feet, with lots of seasonal interest, since the spot is near the front door. The ground is dry, though I'm willing to water every 10 days or so once the plant is established. Dappled shade is a generous term in this case; not a lot of sun gets through. Spring and winter interest are the most important, since other nearby plants have interesting summer and fall flowering and foliage. Thanks for your help!
