I am in zone 3, in Alberta Canada. I can provide: A. negundo (Manitoba/Box Elder) A. tataricum (Hotwings Tatarian Maple -- seeds will not likely breed true) A. ginnala (Amur) Picea meyeri -- These are off my own trees, so they have survived 12 years of Alberta winters. Pinus banksiana (Jack Pine) Pinus contorta var. latifolia (Lodgepole pine) *** I am mostly interested in, and would like about 500 seeds each of: P. sibirica / P. cembra var sibirica P. koraiensis (Korean pine) Abies veitchii from a zone 3 source (I've killed a lot of seedlings, but I have some survivors. Looking for more.) Abies concolor from a zone 3 source If you have others, let me know.
