If you have completed the Ale Googles quest and gathered the harestables, this quest will auto-complete.
You must answer her riddle "Through the eyes of ale you see it. With your hands you pick it. It is wild, noble, golden, emerald and godly."
Most of the riddle refers to the Bountiful Brewday garden shrubs (they have a green particle effect) that you must find and harvest materials from to complete the quest.
The shrubs are can be found near Bar of Brell locations that have open land around them. If the Bar of Brell location is not out in a grassy area (dock at Timorous Deep) check nearby and check riverbanks in most locations as well.
The gathered materials are used to craft items from the recipe books sold by Balin Copperfoot in the Bar of Brell.
The Emerald Clovers are a "rare" material, but the degree of difficulty in finding them may depend largely on any Tradeskill Alternate Advancement you may have and any gear you have equipped; to better understand the degree of variation, see talk page.
