Plants (植物 , shokubutsu) are organisms scientifically belonging to the Plantae kingdom. Unlike the organisms from the Animalia kingdom, plants cannot move on their own and rely on food being brought to them one way or another. Plants generally support almost all terrestrial life on earth and play one of the most important roles in the food chain.

Plants in Seihou
In the Seihou Project, all plants on Earth went to extinction. The only known plant to still exist was the cactus (Cactaceae) (サボテン saboten), where the Cactus Company managed to extract energy from it (called cactus energy) for humanity to continue. Although this is the case, grass and a few trees were still shown to exist throughout the games. The Silk Road (that may have possibilities to have an official connection with the Touhou Project) was shown to have many plants in the background of the Extra stage of Shuusou Gyoku.
- A copy of Voynich manuscript was seen in Oriental Sacred Place chapter 15, depicting a section on plants.
