Diervilla lonicera
Bush Honeysuckle
"
I first encountered this plant on a canoe trip to the French River District in Ontario where in mid-October its foliage was an very intense ruby red. I was later to discover that this plant was available commercially and thus I was able to use it in the A. M. Cuddy Gardens. I have planted in along the edge of the driveway in mass, there it receives little moisture and the baking summer sun; yet it thrives. The bonus are its delicate yellow blooms in spring that resemble those of the true Lonicera species. Periodic pruning to regenerate every five years help to keep it looking fresh. This is one tough, relatively carefree plant.
