BioPlant

The BioPlant is the result of planting the Miracle Seed. The plant's high intelligence and mutation caused the plant to create sub-species and grow uncontrollably.

When defeated, a large green shiny seed is dropped called a BioPlant Seed. With the ability known as Plant Reform, a user can modify the BioPlant Seed in various ways.

Background
According to local tradition, the BioPlant was created by an evil alchemist who was obsessed with BioPlant research. However, based on a warning left by the alchemist, it seems that he eventually gave up. The alchemist then sealed up the plant at his base, the alchemist's cave, with a powerful golem defending it and a warning sign for those who were looking to take the seed.

Volume 1
Motoyasu receives a job to deliver food to Lerno Village which was experiences a famine. Using his game knowledge, he travels to the alchemist's cave to retrieve the "Miracle Seed" to help the village with their famine. He gives the village the BioPlant seed and is praised by the town.

Volume 2
On his mission to get magical clothing for Filo, Naofumi and his party travel to the Alchemist's Cave along with the Magic Shop Owner. They find the empty chest and read the warning accompanying it.

Eventually, Hickwaal notifies Naofumi of a weed killer business opportunity in Lerno Village so Naofumi investigates. They find the entire village covered in thick writhing vines and covered with plant-based monsters. Naofumi sells the weed killer and takes a commission to rid the town on the invasive plants. He kills the main BioPlant which destroys all of the invasive offspring. He then absorbs the remains which give him plant modification abilities. He then modifies the Bioplant to be a viable cross amid a famine and starts selling the seeds and produce.

BioPlant
The main monster which was taking over Lerno Village and is the master-plant from which all other enemy plants were produced.

This main plant looks like a massive tree in the middle of the village which has a giant eye looking down upon the villagers. This plant can control vines like appendages and has incredible regenerative abilities. When this plant was killed, all of its offspring also started to die.

PlantRiwe
The first sub-species produced by the originally BioPlant.

A humanoid creature construct from vines with a large flower growing from the region of its head. The flower releases clouds of poisonous pollen.

Madoragora
The second sub-species produced by the originally BioPlant.

A large creature described as a large, immobile pitcher plant. It releases acidic liquid from its vines, which it would fling at weaker creatures and then, when stunned, would pull them into its gaping mouth.

BioPlant (safe version)
The first modified-species created by Naofumi.

A plant that produces an abundance of red, juicy, tomato-like fruits. Unlike the originally BioPlant its intelligence and mutation ability was dropped to one.

Camping Plant
The second modified-species created by Naofumi and Rat.

A plant that would take on the form of a house when instructed to do so. The plant used photosynthesis to convert sunlight into magic power during the daytime. At night, that magic power could be used to make the plant's flower give off light.

Modified Sakura Lumina
A plant created by Naofumi through splicing together the BioPlant and Sakura Lumina Tree. These trees bypass the geographic restrictions of typical Sakura Lumina trees while still providing the same benefits such as lighting and a power boost for Way of the Dragon Vein magic. These trees look similar to cherry blossom trees and now make a defensive perimeter around Lurolona Village.
