The Yellow Sunflower Top is an end-product of the Fantastic Sunflower plant, a crop that can be grown and cultivated by the players while performing gardening-related activities in the Frontier. There are no alternative methods that players can do to acquire the Yellow Sunflower Top outside of gardening.
In appearance, the Yellow Sunflower Top is the detached top of a sunflower colored yellow. Other than that, not much can describe its overall looks. Unlike other end-products from the Gardening feature, the Yellow Sunflower Top cannot be consumed by the players. Like most items, it can be sold to a selling vendor at a selling price of 2,000 gold.
