its written in Icelandic language, but if you scroll down, the letters a-z give you the latin names of plants growing at akureyri botanical garden. They are at 65 degrees N, still Koppen Cfc (subpolar oceanic), but nearly Dfc(subarctic), and I believe USDA hardiness zone 7. Its especially exciting for me here in kachemak Bay, Alaska, because the summertime climate there is nearly identical to mine here, but about 2 degrees fahrenheit cooler than mine in summer (though slightly warmer in winter), so anything that grows there should theoretically grow here if it is cold hardy enough. This is a great reference for far northern maritime areas and should be useful for people in Anchorage, Southcentral and Southeast Alaska, Aleutians, East and west coasts of Canada, Maine, Scotland, Scandinavia and northwest Russia, and of course Iceland and the Faroes, possibly Greenland. Just compare the hardiness of plants on the list with that of your area. The list itself does not have hardiness, you will have to check that with pfaf.org or another source. I believe everything on the list is zone 7 or hardier. Also, your browser can probably translate the page to English.
I am checking the plants list with pfaf.org and compiling a list of all the plants growing at Akureyri that pfaf has given an edibility rating of 4 or 5, and I'm including some rated 3 if I find them especially interesting. I did the letter A today and collected 23 of the 2 hundred or so whose latin names begin with a on the Akureyri botanical garden species list. If I ever make it thru the alphabet I will publish it here.
thanks, that's helpful. I noticed that when you click on a species name, there is much more information if you are browsing in icelandic. So, clicking on for example 'corylus avellana' while browsing in icelandic and then using your browser to translate gets you a sort of decent translation, but when browsing in english, there is almost no info. there is a section translated as 'experience' for each plant where it tells how the plants have done in the botanical garden.
