I don't find ligustrum to be invasive at all - I have it planted on one
border of my back yard . Keep it pruned and it stays pretty tidy.

Ditto here. I love my Ligustrum trees and hedges. They do very well with
very little water and that's important to me!

Some people hate them tho' but they don't produce any more weeds here
than the hackberries do, and they are very easy to pull up due to their
shallow root system.


Maybe you're thinking of pyracantha? That crap seems to know no bounds...

"Impacts: In many areas of North America, privet easily escapes
cultivation and can quickly degrade native communities by forming
dense monospecific stands [1]. In a survey of federal wilderness
managers, privet was mentioned among "widely reported problem species"
in Alabama, Arkansas, and Kentucky [32].

Japanese privet escapes into natural areas in southern North America
where it can form "dense, impenetrable thickets" and displace native
species [31]. One example is in natural areas around Austin, Texas,
where Japanese privet has invaded intermittent stream bed and mesic
woodland habitats. Its impacts include outcompeting native woody
species such as wax mallow (Malvaviscus arborea var. drummondii),
Mexican buckeye (Ungnadia speciosa), American beautyberry (Callicarpa
americana), small palmleaf thoroughwort (Conoclinium greggii), pecan
(Carya illinoensis), and Texas ash (Fraxinus texensis). Removal of
Japanese privet from these areas has resulted in regrowth of other
native species, including mescalbean sophora (Sophora secundiflora),
Buckley oak (Quercus buckleyi), live oak (Quercus virginiana),
southwestern bristlegrass (Setaria scheelei), toothleaf goldeneye
(Viguiera dentata), white crownbeard (Verbesina virginica), Rio Grande
palmetto (Sabal mexicana), rougeplant (Rivina humilis), and Drummond's
woodsorrel (Oxalis drummondii) [53]."
