Saw Greenbriar is found in tropical, subtropical and temperate areas around the world. It is a thorny vine that climbs trees and fences and can attain heights in excess of 20 feet. It will cover shrubs and other plants forming prickly dense thickets. The green leaves are variable in shape and sometimes have yellowish blotches. The berries are an important food source for birds and other animals, and the dense thickets offer protection and shelter.

This thorny vine is considered a weed by many here in Florida. I find this plant growing in wooded scrub areas along our property line, as well as popping up and climbing around and through the chain link fence. It's hard to eradicate without digging the rhizomes which seem to go deep into the soil.

I found smilax growing wild in my backyard yesterday, in Louisa, VA. It had some pretty black berries still on the vine that the birds and squirrels haven't finished off yet.

An aggressive, high-climbing, tough and woody vine weed that climbs trees and shrubs in east central Texas. Tendrils allow it to climb very high. Stems have spiny thorns and are hazardous to humans. This perennial rhizome sends out underground stems that make roots and shoots at nodes.
When my brother-in-law volunteered to help clean up a Ft Worth nature preserve, he said removing these vines was a near everyday job. Eradication is not easy. Inevitably, they'd come back.
