Last year I planted a venus seedless grape vine I bought from a nursery. It grew a little slower than I expected, but it grew steadily and I started training it up where I wanted it to go, normal stuff really. The longest arm grew somewhere around 3-4 feet in length while the other side did less well (had a natural Y shape when I bought it, and I planted it in the middle of a section of split rail fencing).

It must have grown roots like crazy over the mild winter is all I can say. Its been "awake" for a couple weeks now, maybe a month, and dang. One section has already grown at least a foot of new growth, with at least an inch or two added just about everywhere else. Some of the new growth is even already thicker in diameter than the old woody growth its coming out of, which looks a little odd in spots, but whatever.

Very happy about all that, as I built that fence just for it to climb on, and it looks like this year its going to take it over. I'm even seeing what look like the beginnings of some grape clusters.

Patience does pay off in the end. =)
