Which is weird, right? What with Yuka's "Flower Master of the Four Seasons" title and all. She shouldn't be a candidate in the first place because she associates with all of them.
Do sunflowers bloom in the spring or in the summer?
Mostly they bloom in the summer, as they are planted in spring and take a while to develop to flowering stage. In very mild climates they can even be grown year round, but this is unusual.
