Blindweed
Blindweed is a herb that requires 235 to gather and appears as flower with teal coloured petals, easy to spot for farming. It is usually found near stagnant water like Darkmist Ruins and Verdantis River in Feralas. It can also be found at Un’goro Crater and Maradon, but majority of the spawning points are in Feralas.
