History and Flag
Anubiagender and its flag were created by since-deactivated Tumblr user Dovemogai (formerly Biohazardmogai) and posted on December 17, 2019.
"The colors are typical of the Anubias plants, with the paler colors signifying the early starts, growing outwards into the darker, richer greens, just as the plants physically do."
"Anubiagender" comes from "Anubias", a semi-aquatic plant that grows slowly whilst rooting themselves into wood, etc. "to inevitably become large, beautiful plants."
