Hi Paul,
I got my wisteria about 3 years ago in the sickling pile at the nursery. It recovered nicely and is one of my most prolific growers. It was probably about 2-3 years old from the nursery, so I would say its about 6 or 7 years old now. I would like to see what color and length the flowers will be as there was no tag on it. I would prefer long purple blooms like the one you have. Do you know if it is Chinese, Japanese, or American? What is the current age of yours if I may ask? I would also like to obtain about the same trunk diameter of yours before putting it into a bonsai pot.
Tiberious,
This wisteria was collected in 1988 from the bank of a stream not far from my house. The vine had grown 80 feet up into the canopy of the surrounding trees.
For reference purposes, the pot measures 18" across. The base of the trunk is approx. 5 1/2" in diameter.
At this point, I am pretty sure that this is a Chinese wisteria. I thought for many years that it was the American variety. This particular wisteria has smaller racemes than the typical Chinese wisteria and the leaf configuration seemed to match that of the American variety. However, last year I let a seed pod mature, which was something I don't normally do. The seed pod was a perfect match for the Chinese variety.
To fatten up your wisteria, put it in the ground and let it grow. Once you put it in a pot, the trunk diameter will not increase very much.
I hope this helps.
Paul
