In http://www.ehow.co.uk/facts_7809091_time-plant-wisteria.html I read

"Warning

Do not grow wisteria near gutters, where the runners can climb them and
clog them. Do not plant Chinese wisteria or Japanese wisteria, as these
plants are invasive and can choke out the local plants. Instead, choose
wisterias that are native to the United States.
"

I think all the Wisteria I have seen online are Chinese/Japanese -
haven't noticed any US natives.

Presumably even though this is a '.co.uk' site it is relaying US-centric
advice?

I was looking for when to plant out Wisteria as I noted the supplier in
the previous thread only supplied plants for the first six months of the
year.

You will not be surprised to hear I think that advice is garbage!

Yes, I thought it looked a bit strange.

I was mainly intrigued by the prospect of US native Wisteria and wondering
if anyone had grown them over here, because some parts of the US have a
similar climate (although large parts don't).


Wisteria fruiticans. It has smaller flower trusses than the oriental
varieties and needs a good amount of heat to flower well and lacks scent,
(there is a sub species with some scent), it is not often planted in the UK
but does make beautiful bonsai.

The Americans find it less invasive than the two oriental wisterias which
with their much hotter summers seed freely, W. sinensis is a huge plant and
can be damaging in the wrong place
