I have been trying to find white or pink wisteria (mainly white) cuttings, but if i do find some i need to know how to make it root. any help?
Here's a link for a good how-to for rooting wisteria cuttings.
Before you start growing wisteria, be sure you aren't biting off more than you can chew. Know what kind of wisteria it is, and what its growth habit is. Here are a few things you should know (if you don't already):
Wisteria layers quite easily, so if you can find a piece of the vine that has touched the ground, you may be you may be able to dig it up, roots and all. If you're not in a hurry, you can layer a part of a low-hanging vine yourself. Put a pot of soil under the vine, place the vine in the soil, cover the vine with soil, and put a rock on it to keep it weighed down. Check in a couple of months.
It can take several years for a cutting to bloom. From seed, the vines remain in a juevenile stage for 10-15 years before they are old enough to bloom. Plants grown from cuttings can shave several years off of that timeline, and a layered piece of vine can give you an even bigger head start.
Wisteria vines can get quite large, and live a long time. One vine in Japan has been dated back to the 1870s, and covers more than half-an-acre. They require very strong supports, and can collapse a simple wood arbor under their weight. In some states, wisteria is considered invasive or noxious.
Wisteria has to be slightly root-bound for best bloom performance. If yours doesn't bloom after a few years, try root-pruning it. They don't like to be overwatered, and actually prefer soil that is nutrient-poor.
The 2 most popular kinds of wisteria are Japanese and Chinese. The Japanese wisteria, Wisteria floribunda, is the more fragrant, but of the two, has smaller flower clusters (even though the name, floribunda, would suggest otherwise). The Chinese wisteria , Wisteria sinensis, has larger flower clusters, and sometimes blooms before the vine (actually a liana) fully leafs out, but is not known for its fragrance. The flowers can get frost-nip in areas of the country where winter lingers. Interestingly, the vines of each species wind in different directions. The Chinese wisteria twines Counterclockwise (remember 'C' for Chinese, 'C' for Counterclockwise), and the Japanese wisteria grows clockwise (remember by making a 'J' in the air with your finger, and the hook heads clockwise).
Here is a link to a fact sheet about how to grow wisteria
Do your research before taking on the commitment of wisteria. It can get out of hand quickly. In Olympia, WA, there is a wisteria that has escaped cultivation. It has taken over a clump of Douglas-fir trees, nearly reaching the top - a height of about 100 feet. Wisteria can cover a barn. If you plant it under your eaves, it can rip your roof off. The goal with Asian wisteria is to 'control' them - a lifelong commitment. I suggest that you look for cultivars derived from our native American wisteria that are smaller (though non-fragrant) and easier to maintain, such as 'Amythest Falls'.
