Asian Bush Honeysuckles
Lonicera maackii, L. morrowii, L. tatarica
Honeysuckle Family (Caprifoliaceae)
Fruits: Jun–Jul, Oct–Nov (L. maackii)
Native Range: China, Manchuria, Korea
Introduction: Tartarian in 1700s, Amur and Morrow’s in late 1890s. Promoted by USDA for wildlife habitat and shelterbelts. Mid-Atlantic Range & Habitats: Open woodlands, old fields, forest edges, hedgerows, throughout the region.
Several similar species of bush honeysuckles of Asian origin occur in our region. These shrubs leaf out early in the season and hold their leaves longer than most native deciduous shrubs, thus reducing light availability to other plants for a long period of the growing season. Recent studies have shown that chemicals in L. maackii are capable of inhibiting germination of other plants. The nesting success of birds nesting in Asian bush honeysuckles may be reduced because the plants provide less protection fromnest predators. In addition, foraging birds choose honeysuckle fruit as readily as some native species with greater caloric content. Honeysuckle seeds may be dispersed over long distances by birds and deer.
- Leaf Margins: Leaf margins entire
- Fruits: Fruit a red (usually) to yellowish round berry

The yellow flowers of our native Bush-honeysuckle (Diervilla lonicera) are in groups of 3–7 and turn reddish with age. The invasive honeysuckle species all have white to yellow flowers, with the exception of Tartarian Honeysuckle (Lonicera tatarica) that can have white to pink flowers.
