BioPlant

Bio Plant is the general name for all common plants, but it is also a boss level monster that looks like a gigantic tree from a distance but up close it is revealed to be a giant vine-like creature. When it was initially planted it was able to produce a tomato like fruit which saved a village on the brink of starvation, but since it had the ability to mutate it did so creating a monster. It is able to create two familiars, the Plantriwe and the Mandoragora, that act like extensions of itself. In the center of the trunk like structure are huge eyes which will simply regenerate if they are destroyed using a physical attack. It is destroyed by scattering herbicide on all of its roots. When it is defeated it and it's familiars wither and die. In it's place a shiny seed called a Bio Plant Seed is dropped which is able to be modified greatly by Naofumi. The modified versions of the Bio Plant loose the ability to create familiars and are used to prevent famine in multiple places including Rock Valley. Found in chapter 『Chapter 39』 of the web novel.
