Harvesting a sunflower will drop 1 Sunflower, and 0-2 Sunflower Seeds. The total seed drop often numbers around 75% to 90% of the number 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.
Sunflower is used in the spool of the Sewing Machine with Cloth in the feed to create a dyeable Long Dress. It is a yellow dye when used in the spool of the Sewing Machine with a dyeable clothing item in the feed. It can be placed in the yellow dye pot at Emily's and Haley's house for use in dyeing.
If placed within proper range of a Bee House (5 squares in any cardinal direction), a Sunflower will cause the Honey produced to become more profitable.
