Northern bush honeysuckle occurs from Newfoundland west to Saskatchewan; south to Nova Scotia, New England, Delaware; and in the mountains to Virginia, North Carolina, and Tennessee; and west to Ohio, Indiana, Illinois, and Iowa.
This plant is present in at least 34 states/provinces in this country.
Northern bush honeysuckle is a native, deciduous small shrub that usually grows from 2 to 4 feet (0.6-1.2 m) tall. The branches run close to the ground, ascending slightly. The fruit is a dry, woody, dehiscent capsule.
The peak flowering season for northern bush honeysuckle is from early June to early July, but flowers have opened as late as August in Michigan. The fruit matures and releases seeds in September.
