Topic: Pruning, Shrubs
Title: Perennial summer blooming plant for Livonia, MI
Answered by: Barbara Medford

QUESTION:

I want to find a plant that I can cut back in the fall, will come back in the spring, flower throughout the summer, be a medium size plant, no taller than 48", about 36" in diameter. It would get full sun in the morning but afternoon time the shade kicks in. What plant/perennial can I plant? Something with color and full.

ANSWER:

Ordinarily, when we speak of perennials, we are thinking of herbaceous flowering plants that bloom, set seed, die back to the ground in winter, and re-emerge from the roots in the spring. Your specifications sound more like a blooming bush, which would likely be deciduous, losing its leaves in the fall, but could be of the size you want. We will go to our Recommended Species for Michigan, and search on "shrub" under habit, "part shade" (from 2 to 6 hours of sun a day) under Light Requirements and bloom times of June, July and August. That won't mean the plants we find will bloom all summer, but will bloom at some point during those months. We will list these for you and then you can follow the plant links to the individual pages on each individual plant, learn what size it can be expected to reach, colors, etc. When we ran this search, we got 17 results, and chose 4 that came closest to your specifications. You can repeat the process, using different specifications and make your own choices. Most of these shrubs will benefit from some pruning back in the fall, but some may be better pruned in the spring after they have bloomed. Your USDA Hardiness Zone appears to be Zone 5b (average annual minimum temperature of -20 to -15 deg. F) so any plant recommended for Michigan should be all right in Wayne County in Southeastern Michigan.
