Talupia Tangio is one of the first harvestable flowers available to the players in the Herblore skill path alongside Talupia blancus and Talupia crimson.
They are used to craft the first available Speed Potion with the help of these two herbs. They are also one of the ingredients in the ever so important Prayer potion. Giving 2 XP per harvest, it isn't the most effective way to farm Herblore XP , but very versatile as an ingredient, and you will need large amounts of it on the grind for 99.
Farming locations for Talupia Tangio include Lumbridge, Draynor village, and Varrock. Similar to Talupia crimson; the most efficient spot to farm Tangio is outside Draynor village bank as well.
