Grows as a vine, not a shrub. There are a number of native vining honeysuckles in Michigan:
- Lonicera caprifolium (Italian Woodbine). Only found in one Upper Peninsula county.
- Lonicera dioica (Limber Honeysuckle). Seeds are very similar to the non-native bush honeysuckles and may not be distinguishable.
- Lonicera hirstuta (Hairy Honeysuckle). Found mostly in northern Michigan.
- Lonicera sempervirens (Trumpet Honeysuckle).
- Lonicera reticulata (Grape Honeysuckle). Only found in two Upper Peninsula counties.
Seeds of L. japonica present in bird fecal samples at the Rouge River Bird Observatory, Dearborn, MI.
