Fayeth is the gardener who looks after the tree farming patch east of the Combat Academy in Lumbridge. She also sells some basic farming materials. Fayeth is part of G.A.G., the Group of Advanced Gardeners.
She appears to be holding secateurs, but hers are of a silver colour, are wieldable, and do not have the brown leather cover on the bottom half like the icon shows.
Fayeth also sells basic farming tools, which can be accessed by talking to her and asking Can you sell me something? It is not an actual shop and it has no set stock; each item has to be bought individually through the dialogue.
