Redberries

Redberries are items used in making red dyes and making Redberry pie.

Redberries are acquired by the following:
 * Are sold at the food store on the south side of Port Sarim, if there are some in the players' stock.
 * Can be picked from the two redberry bushes on the southeast side out of Varrock's walls.
 * Redberries can also be grown with the Farming skill at level 10 in any bush patch.

You can use redberries to make red dyes. Just ask Aggie the witch in Draynor Village to make red dye and bring her three clumps of redberries and 5 coins as a fee. Redberries can also be used to make redberry pies; The Knight's Sword quest requires you to make a Redberry pie.
