Gardeners' Notes:

Negative coriaceous On Feb 11, 2014, coriaceous from ROSLINDALE, MA wrote:

Who would want to grow a bush honeysuckle without fragrant flowers? The flowers of this species are small and have no fragrance. If you have a highly fragrant bush honeysuckle, your shrub is L. fragrantissima.

If this grows in your yard, odds are good that it was planted by some passing bird and not by conscious choice.

The gang-of-four Asian shrub honeysuckles that are widely invasive in North America (L. maackii, L. tatarica, L. x bella, and L. morrowii) are dowdy shrubs without fragrance. They come with a host of pests and diseases, foremost of which is the Russian aphid that causes disfiguring witches' broom. Most descriptions exaggerate the ornamental value of their flowers.

Planting of this noxious weed species is prohibited in four states. Together with the other invasive honeysuckles and buckthorn, it destroys natural habitat and shades out our native woodland wildflowers. It impoverishes our once rich native flora and reduces its capacity to support wildlife.

Native to Japan, Korea, and Northeast China, Morrow's Honeysuckle is highly invasive in the Northeast and Midwest of the United States. I am battling it like crazy in our woods in Indiana. Morrow's Honeysuckle thrives at the edges of forests, roads, or other natural or man-made barriers, but is not limited to them, and is found in both mature and disturbed forests. In some areas, Morrow's Honeysuckle is the dominant plant species, especially in areas of disturbed ecological succession. It is suspected that Lonicera morrowii is allelopathic, and may capitalize on disturbed ecological succession by establishing itself and then preventing the growth of plants underneath it. With a sufficiently established thicket of honeysuckle, even other shade-tolerant, invasive species, such as Fortune's Spindle have difficulty growing underneath it, whether due to its suspected allelopathic activity or through soil depletion. Due to its early leafing, Morrow's Honeysuckle is particularly harmful to spring ephemerals, flowers that evolved to bloom briefly in the spring before other plants leafed out.

If you live in North America, please choose a native bush like Bottlebrush Buckeye, Ninebark or Black Chokecherry instead.

Morrow's Honeysuckle Lonicera morrowii is naturalized in Texas and other States and is considered an invasive plant in Texas.

Positive langbr On Apr 21, 2004, langbr from Olathe, KS (Zone 6a) wrote:

A deciduous shrub form of honeysuckle that flowers in late Spring. Flowers are extremely fragrant and very sweet smelling as is typical of honeysuckle. Bright red berries develop in June/July. This shrub is very attractive to bees during flowering stage and birds during fruiting. Makes an excellent privacy hedge or screen. Native of Japan.
