Description
 
 

Morrow’s honeysuckle is an erect, 3 to 10 tall, perennial shrub that rises from shallow roots. It sometimes forms dense thickets.

The branches are straight and hollow. They are light green and covered with soft, fine, short hairs when young. Older branches have shaggy, grayish-brown bark.

The leaves are opposite, untoothed, oval or oblong, and 1 to 2 long. They are bluish-green on the upper surface and downy on the underside.

The flowers occur in pairs arising from leaf axils. They are white but turn yellow with age.

The fruit is a red berry.

Similar Species

 
 

Aside from northern bush honeysuckle, all honeysuckles native to Minnesota are vine-like, not shrubs, and have twining branches.

Tatarian honeysuckle (Lonicera tatarica) is also a non-native species. It has white or pink flowers that do not turn yellow with age. Its leaves are entirely hairless.

 
     
 
Habitat
 
 

Deciduous woodland borders, savannas, thickets, fence rows, urban vacant lots, railroads, roadsides. Full sun to partial shade.

 
     
 
Biology
 
 

Flowering

Pests and Diseases

 
 

Honeysuckle aphid (Hyadaphis tataricae) causes a witches’ broom of stunted leaf and stem growth at the end of shoots.

 
     
 

Defense Mechanisms

 
 

Morrow’s honeysuckle plant is thought to be allelopathic, releasing a toxin in the soil that inhibits the growth of other species.

 
     
 
Use
 
 

The red dye rhodoxanthin, in the fruit of Morrow’s honeysuckle, is responsible for an unusual orange hue in the wax spots of cedar waxwings in the last 35 years.
