The Sunflower is a flowercrop that grows from Sunflower Seeds after 8 days. Unlike other flowers, they don't affect the type of Honey produced by nearby Bee Houses. Harvesting a sunflower will drop 1 Sunflower, and 0-3 Sunflower Seeds. In quantity, the total seed drop usually numbers around 75% to 90% of the count of sunflowers harvested.
Sunflowers may be planted in both Summer and Fall. There is no difference in their behavior in either season.
If a Sunflower plant (of any growth stage) is in the ground on the 28th of Summer, it will continue growing on the 1st of Fall as though nothing had changed. Fertilizer in the ground underneath a Sunflower plant on Summer 28 will not disappear on Fall 1.
