Ajisa

Ajisa, called Hydrangea Plants in the Viz version of the Dragon Ball manga, is a plant on planet Namek. Ajisa are named after hydrangea plants (ajisai in Japanese), that snails are known to like.

Overview
These crops were destroyed by a giant storm that ravaged the planet in Age 261. Dende describes this scenario to Krillin and Gohan during dinner when Krillin wonders why Namekians cultivate this plant since they do not need food and only drink water. Initially, Krillin thought that the crops were supposed to be consumed by the Namekians, but Dende reveals that the crops are cultivated only to enhance the beauty of their planet.

Video game appearances
In Dragon Ball Z: Battle of Z, Ajissa Sapling is an item that slightly increases Ki Blast power.
