Does anyone know the best way to root wisteria?

Rooting Wisteria Plants. Prepare a pot with well-draining potting soil that has been thoroughly moistened. Dip the rooting end of the cutting into rooting hormone. Using a finger or a stick, make a hole in the potting soil, then place the wisteria cutting in the hole and gently press the soil in around it.

I've gotten a few starts from mine by laying a vine/branch on the ground & putting a shovel full of soil about a foot away from the end of the vine. After a few months, it'll send out roots from where it's burried & can be snipped off & planted elsewhere.

If she's a friend, I recommend not giving her this plant. Wisteria is a very aggressive plant that will eventually overwhelm any structure it gets near. If you still want to give her this plant anyway, tell her to plant it away from any structure. They really root well, and it will almost be impossible to get rid of it after it gets going.

Wisteria is EASY to get started! Simply cut a few roots, lay in some potting soil in a large pot, keep watered and it will grow. Wisteria is one of those plants that grow just about anywhere, in most soils. That said, it is easy to start going in pots. Actually, it can be quite invasive if not kept trimmed. Good luck, and happy planting!
