Dense, multi-stemmed shrubs, deciduous shrub that is 6-12’ tall. Young stems are slightly hairy and light brown while older stems may have shaggy, peeling bark and are often hollow between the nodes.
OverviewOther names for this plant include:
- Common names: Tartarian honeysuckle, bush honeysuckle
- Scientific names: Lonicera sibirica; L. tatarica var. latifolia
- Invade a broad range of habitats, including forest edges, open woods, fens, bogs, lakeshores, roadsides, pastures and old fields.
- Tartarian honeysuckles alter habitats by decreasing light availability, depleting soil moisture and nutrients, and possibly releasing allelopathic chemicals that inhibit the growth of other plants.
- Eurasian bush honeysuckles have been widely planted as ornamentals and for wildlife habitat. Commercial propagation continues with many cultivars available from nurseries.
- Hybrizes with L. morrowii to create L. x bella which is also invasive
Classification in Wisconsin: Restricted
Species Assessment Groups (SAG) were assembled to recommend a legal classification for each species considered for NR 40. The recommendation for Tatarian honeysuckle was based upon this literature review developed by the department.
Leaves: Opposite, oval or oblong and untoothed. Leaves may be hairless to downy and green or blue-green. Leaf bases are slightly heart-shaped to nearly straight. Leaves come on 1 to 2 weeks earlier in spring and stay on later in fall than the leaves of native trees and shrubs.
Flowers: Fragrant, tubular and arranged in pairs at leaf axils. Reddish pink or white, turning yellow with age. Bloom mid- to late spring.
Fruits & seeds: Red to orange berries occur in pairs at leaf axils and contain many seeds. Readily dispersed by birds.
Roots: Fibrous and shallow.
Similar species: Native Lonicera shrubs have shorter, sparser growth forms and white pith in stems. Native Diervilla species have yellow flowers that turn red with age, fruits that are elongated capsules, and grow in dry or rocky sites. Native species develop leaves 1-2 weeks later, drop them earlier in the fall, and often have solid stems. L. morrowii, L. x bella and L. maackii are also invasive bush honeysuckles. They are all very similar except for slight differences in flower color, and leaf downiness.
Mechanical: Small to medium-sized plants can be dug or pulled by hand or with a leverage tool. Prescribed burns in spring kill seedlings and top kills older plants.
Chemical: Cut-stump treatment with glyphosate; cut-stump treatment or basal bark treatment around each stem of the plant with triclopyr ester. Treat foliage with glyphosate in early spring prior to leaf out of native species.
