Border Privet - Ligustrum obtusifolium This shrub is an invasive species that is banned in Connecticut and is not considered to be naturalized. Yet, I found it growing wild. This plant is able to escape cultivation and rapidly form dense thickets that can crowd out native species, which is why it is banned in Connecticut.

It has elliptic-shaped leaves and dark blue fruit (when ripe), which persist on the branches throughout the winter. The fruits on this shrub were not yet ripe.
