Answer:

I couldn't find the most invasive, but found a list of invasive ones and their alternatives:

Explanation:

  • Norway maple (Acer platanoides)
  • Autumn olive (Elaeagnus umbellata)
  • Multiflora rose (Rosa multiflora)
  • Glossy buckthorn (Frangula alnus)
  • Burning bush (Euonymus alatus)
  • Blunt-leaved privet (Ligustrum obtusifolium)
  • Yellow flag iris (Iris pseudacorus)
  • Shrub-like honeysuckle (Lonicera morrowii, L. x bella,
    L. maackii, and L. tatarica)
  • Bishop’s weed or gout weed (Aegopodium podagraria)
  • Oriental bittersweet (Celatrus orbiculatus)

Native alternatives to plant:
- Red maple (Acer rubrum) replaces Norway maple
- Bayberry (Morella spp.) replaces autumn olive
- Climbing prairie rose (Rosa setigera) replaces multiflora rose
- Alternate-leaved dogwood (Swida [Cornus] alternifolia)
replaces glossy buckthorn
- Highbush blueberry (Vaccinium corymbosum) replaces burning bush
- Inkberry holly (Ilex glabra) replaces blunt-leaved privet
- Blue flag iris (Iris versicolor) replaces yellow flag iris
- Serviceberry (Amelanchier arborea) replaces shrub-like honeysuckle
- Golden Alexander (Zizia aurea) replaces bishop’s weed
- Trumpet creeper (Campsis radicans) replaces oriental bittersweet
