B) Exactly where in "Chinese high altitude" locations might this be? Thanks Jim W. Dr. James W. Waddick 8871 NW Brostrom Rd.

She has a lot of customers on arisaema-l. She sells T. kunmingense, which is a small horsfieldii and from Yunnan. I am sure there is a goodies list out for the season 2000-2001. Many Arisaemas on that. +More > B) Exactly where in "Chinese high altitude" locations might this be? Dunno exactly but the Chen Yi plants are from 2100 m altitude. That is an indication of temperateness. Cheers, Wilbert

However, its complicated by whether or not you are talking about East or West Coast, proximity to a large body of water (especially upwind of the site), etc. For instance, there are pockets of zone 6 in close proximity to Lake Ontario which are surrounded by zone 5. These pockets are at the same general altitude, they happen to lie in the "snow shadow" of the lake on the prevailing winds. You see the same thing in southern New York State where the Chenango River meets up with the Susquehanna. Right at the river, its zone 5b (borders on the edge of 6) while most of the remainder of the county is zone 4. Forty or 50 miles away to the south, west or north its zone 5b again and these areas are typically higher in elevation. While I lived in that area, I had a devil of a time adapting to the climate. All the stuff which was supposed to be hardy in the "area" struggled. We finally gave up and stuck with only zone 4. Here in Atlanta, the city center is nearly a zone warmer than the surrounding suburbs. To the south of the city its lower elevation, to the north higher yet the area 30 miles south of the city has distinctly colder winters.
