Seeds of the Manchurian walnut.
The Manchurian nut is a tastier and colossally hardy relative of the Walnut. Nuts are distinguished by a very strong shell, greater fat content, a very soft and pleasant taste, they do not have that unpleasant tart, astringent, bitter taste, like walnuts.
Eating a kilogram of Manchurian nuts is not difficult at all, while you are unlikely to want to eat more than 100 grams of walnuts.
The tree grows very quickly, from 0.5 to 1 meter in 1 year.
It seems that the Manchurian nut did not decide who it would be better for him to be - grass or a tree, so he took the best from both. The tree is extremely unpretentious, and grows quickly and never gets sick with anything. Ego leaves smell very tasty, purifying the air from harmful microorganisms with their smell.
On top of the armor of the Manchurian nuts there is a thick soft peel, which can be infused with vodka, getting a tasty, high-value, high-vitamin, immune-enhancing brown liquid, vaguely reminiscent of mountain mumiyo in smell.
Grows in poor clay soils, about 2-3 inches of poor black earth is sufficient. Comfortable growing and fruiting temperatures in summer from +10С to +25С, in winter from -40С to -1. Rain and wind are familiar to him. Grows well in the shade.
(Seeds are taken only from plants growing in the wild taiga.)
