The stinging nettle you can pull from seed itself. But that's a tedious matter. If you enjoy it, have the space and a little patience, then you should give it a try.
The stinging nettle has very decorative foliage, but less beautiful flowers. That is why they are often removed in the beginning. Thus, the plant "wastes" no power of flower and seed formation and can instead focus on lush growth. The collection of seeds of their own plants usually fails.
