Ferroustry 1.15.2/1.14.4

The Ferroustry mod will add trees-ore to Minecraft. There were already mods for growing ores, but these are basically all kinds of sprouts, right there are full-fledged trees that look even more unusual. If you don’t need ore, then you can use these trees as a decor on the house territory, especially since there are a lot of them (like ores, in general).

You can get ore with an ax (best to make a diamond ax right away) and then, as usual, these blocks can be remelted.
