This composition is beautiful! The penstemon and daylily 'American Revolution' echo the sand cherries foliage and at the same time offer contrasts in foliage form. I really like how you mix shrubs, small trees, and evergreens into your flower borders -- or maybe its the way you mix flowers into your shrub borders. To me it is a balanced, natural look.

I try to use small trees and shrubs in my gardens. Also, I have a good number of dwarf conifers that I mix in the gardens. The photo is several years old and part of my original "RED" garden. The daylily in the center is 'Endless Heart'. The tree grew to be a little to big so I removed it. Here is a photo from a few days ago from a slightly different angle. The daylily in the lower right corner is 'American Revolution' and the daylily in the center is 'Endless Heart'. In the upper left are a couple dwarf conifers...

Dwarf conifers are a great idea esp. here in Michigan. They provide something to look at / keep on framing the space even in the winter.
