Honeysuckle Family

Morrow’s Honeysuckle (Lonicera morrowi). Also called Bush Honeysuckle. A tall bush (six feet or more) with flowers very much like those on Japanese Honeysuckle, both white and buff on the same bush. (Like Japanese Honeysuckle, it came from Japan.) It grows at the edge of the woods, and is particularly fond of roadsides.

Tartarian Honeysuckle (Lonicera tatarica). A noxious weed in many places, but rather uncommon here so far, especially compared to the ubiquitous Morrow’s Honeysuckle (Lonicera morrowi). The pink flowers of this species are distinctive, although it may also produce white flowers, in which case it may be much harder to tell from Morrow’s.

Japanese Honeysuckle (Lonicera japonica). Originally a cultivated Asian import, but now as much a part of the American landscape as the dandelion, this weedy vine covers hillsides and infiltrates hedges throughout the city. It is remarkable for bearing two different colors of flower on the same stem. Children know that a drop of pure, sweet nectar may be carefully extracted from the base of the flower.

☛More recent references place the Viburnums in the family Adoxaceae or Viburnaceae.

Viburnum lentago

Viburnum prunifolium

Highbush Cranberry (Viburnum trilobum). Not really a cranberry, but it has berries that can be a good substitute for cranberries. The leaves are much like the leaves of Red Maple (Acer rubrum), and the flowers come in dense cymes. Most of the flowers are tiny, but the outer flowers in each cyme, which are sterile, are immensely overgrown, making the whole cyme much more showy and a much more attractive target for pollinators.

Viburnum acerifolium

Viburnum dentatumSouthern Arrowwood (Viburnum dentatum). One of several Viburnum species found in our area; this one is not recorded in the literature as occurring in Allegheny County, though it is known to occur in neighboring Butler County. Nevertheless, these bushes did grow in Allegheny County, near the edge of the woods on the grounds of Harmarville Rehabilitation Hospital. The nearly round toothed leaves are a clue. Viburnum recognitum, which may also grow in our area, is sometimes classified as a variety of Viburnum dentatum.
