How To Grow Sunflowers

Sunflowers (Helianthus annuus) 

It's no surprise that sunflowers have always been the go-to cut flower globally. They're ridiculously easy to grow, thriving in the sweltering summer and early fall. These flowers bloom like crazy and demand almost zero attention. They're basically the happiest flowers you can plant.

Over time, breeders have whipped up a bunch of stunning sunflower varieties that go way beyond your typical yellow-orange ones with a black center. 

Adored by pollinators and birds, adding a few to your flower garden is a no-brainer.
