Tumbleweed Mod (1.18.1 and 1.17.1), adds tumbleweed to Minecraft. Tumbleweed is a structural component of the above-ground anatomy for a variety of plant species. It is a diaspore which, once mature and dried, separates from its stem or root and tumbles in the wind.
Tumbleweeds are found in areas with dry, hot biomes and spawn from dead bushes. Upon harvesting, they will drop random goodies. You can customize the drop of items by editing your config file.
