We have cable. That’s why I’m such an intellectual force to be reckoned with. I have at my fingertips access to in-depth research tools like the Hallmark Channel where I learn what makes women tick (something to do with automatic air fresheners), the Speed Network for the latest developments in dirt bike oil filters, and the History Channel (it’s not just about pawnshops).

But I’ve yet to see a documentary on the ancient migratory trail of the Wisterians, who evidently passed through Santa Barbara, leaving barely a trace.  Without a reliable body of research I can only conjecture that they appeared about 14,000 years ago but were out-completed by the Clovis civilization (purveyors of fine stone spear points). Or the Clovis folks just had better PR.

But back to the Wisterians. They must have been a gentle people as evidenced by their love of sweet smelling, pastel colored plants.

“Why Professor Goodnick,” you challenge incredulously, “with what evidence do you support your hypothesis?”

Fair question. You know how in the first Indiana Jones movie he finds that metal thingy, puts it on top of a stick, and on just the right day at just the right time the sun shines through and illuminates the secret location of the Ark of the Covenant? It’s like that, except instead of calculating sun angles and seasons, the math-phobic Wisterians planted wisteria vines along their migratory route to mark their path.

How else do you explain the sprawling purple wisteria vines that are at this moment bursting forth along Highway 101, the coastal route through my fair state? They’re scampering up tangled trees, showering branches in luscious lavender-colored, perfumed tentrils. Like Hansel and Gretel breadcrumbs, those clever Wisterians turned their love of plants into a pre-GPS way-finding technology. Of course, if they came back at any other time of the year, they’d be hopelessly lost.

The Wisterians couldn't have chosen a lovelier, more sweet-smelling signpost.

14,000 years later, the Wisterian's original trail has been replaced with concrete and steel.  

As any seasoned researcher knows, you have to test alternative theories before declaring the discovery of a new unknown civilization. Those are the rigors of academia. So I called Martin Sanchez, regional superintendent for Caltrans, overseers of California's state highways.

“Did you guys plant the wisteria?” I asked.

“Nope, they’ve been there forever,” came his unhesitating reply. Hmmmm, “forever” or maybe only 14,000 years? The pieces were falling into place.

“Did you guys intentionally leave it when you did that major clean-up a few months ago?” I had noticed a mass pruning of the strip along the shoulder in early fall and my heart sank. I imagined that an insensitive supervisor was fed up with this rampant climber and dispatched his ninja chainsaw assassins. But the wisteria survived, diminished, but charging back to its former glory.

Explaining Caltrans’ roadside maintenance protocol (his words) he told me, “If it’s part of the original design, we leave it. If it’s not causing problems, we leave it. If it contributes to screening, we leave it. If it encroaches, it’s gone.”

He didn’t know who had planted the original vines and in my years in SoCal landscaping I’ve yet to see a wisteria sprout from an errant seed. Which conclusively proves my theory: These profuse grape-like flower clusters MUST be the legendary Lost Vines of the Wisterians.

There are two common species in that grow in my zone (Sunset 24 / USDA 10): the purple-flowering Wisteria floribunda, and the white-flowering Wisteria sinensis. The Chinese connection is intriguing and might require deeper digging—perhaps the Wisterians traveled across the Bering Strait in search of a better life, swinging on the strong, flexible strands of their namesake vine. We’ll go with that, since you’re probably eager to know how to grow this beauty.

The Wisterian word for the plant meant "vine that has purple flowers that gradually fade to lilac, then white, emitting a subtle fragrance, but attracting bees, so don't put it where people allergic to bees hang out."

Buy a plant, dig a hole and put the dirty part of the plant (not the green part) down in the hole. As long as the plant gets at least a half-day of direct sun and is kept moderately moist for a few growing seasons, you’re cruising. The lower stems eventually turn into trunks as fat as a small tree and the vine can reach forty feet in length if given something to wrap around. (Keep slow-moving children at least 50 feet from the base.) It’s a twining vine so it needs stout columns and beams to assure its success.

So, I hope you've learned something from my vast plant knowledge and in-depth research. You can see why I’m a recognized expert in all things chlorophyll and am feared by real anthropologists. I might not have a bunch of scholarly abbreviations after my name, but I do have cable.
