Do let me know of any suppliers of forest garden plants and perennial vegetables that I have missed off this list.
Note that, post Brexit, nurseries have warned that they will not be able to deliver plants from the UK to the EU or vice versa. Seeds should not be affected.
Andrew Lear, also known as Appletreeman, supplies a wide range of apples, pears, plums, and damsons suitable for Scottish growing conditions, including a number of old Scottish varieties brought back to the country for the first time in many decades. Also some nuts, native trees, hedging and soft fruit. He is based in Perthshire.

Chiltern Seeds are based in Cumbria and have a wide range of seeds, including both ornamentals and useful plants. Where B&T World Seeds (below) and Chiltern both have a variety, Chiltern is usually cheaper for UK delivery. Their catalogue is worth getting for its entertainment value alone. A similar seed supplier worth checking is Plant World Seeds.
B&T World Seeds are based in France and carry a huge range of seeds. If you can’t find it anywhere else, try B&T.
Myrrhis Permaculture Garden in Denmark supply seeds of perennial vegetables. The site is in Danish but autotranslate, Latin names and pictures make it usable without needing to go to Danish classes.

Oikos Tree Crops, in southern Michigan, sell not just trees but also soft fruit and some perennial vegetables. They have an American persimmon from northerly seed sources for northerly gardens. They only sell plants within the US but their website says that they will send seed outside at the buyers risk.
One Green World sell fruit, nuts and perennial vegetables as plants or tubers from Portland, Oregon.
In Washington state both Burnt Ridge Nursery and Raintree Nursery sell fruit and nut trees and soft fruit. Raintree have a few other unusual edibles besides. Far Reaches Farm sell perennials in pots. They are not specifically for edibles but have a very wide range and come up in a lot of my searches for the more obscure plants that I am trying to get hold of. I just wish they delivered to Scotland!
Chileflora, a website about the flora of Chile, has an associated shop which supplies seeds from this cool temperate corner of the southern hemisphere to the rest of the world.
