Ranarr weed detail

Ranarr weed is a herb that can be cleaned at level 25 Herblore. It is the fifth lowest level herb available, yet is one of the most valuable herbs in the game, as it's widely used in the Herblore skill to make prayer potions when combined with snape grass. It can also be combined with white berries to make defence potions, although this is a major loss of money, since ranarr weeds are so valuable.

Due to its value, this herb is often grown by players with level 32 in Farming by planting ranarr seeds in the various herb patches throughout RuneScape, and so ranarr seeds are often in high demand as a result. However, it is also an uncommon drop from various monsters.
