It this a vine? A sticker bush? Give me a guess.
Yes, it trails like a vine, even putting out little tendrils to help it climb. But it has the protection of thorns, giving the plant the common name ‘catbriar’.
It’s a Smilax species that also goes by the name greenbriar. Miz Flora says old timers called it prickly-ivy, but I don’t hear the younger squirrels use that name there days. Bu tthse prickles do make it a pain to get rid of.
