Identify Age of Wisteria
We bought a house with wisteria growing out back. One of our gardening friends commented to us, "Wow! I've never seen such a trunk on a wisteria! How old is that thing?" The base is easily 48 inches around, and some of the vine wraps that go up the arbor are about 11 inches around. Is there a way to tell how old the wisteria is? The house was built in 1955, so we know it's less than 61 years old, but we're not sure of its age otherwise. Thank you. -Gloria

My research does not find any way to determine the age of a Wisteria Vine.
There are reports of vines upwards of 140 years of age.
