The Mongolian Sunflower is one of biggest sunflowers you can get! These Heirloom favorites get beyond huge with the seeds over an inch long; the heads get up too two feet with 16 to 18 inches, being common the stalks average over 12 feet. Give these lots of sunlight, loose soil, and water if you want the biggest sunflowers ever. Happy growing!!!
this variety holds up good in windy areas.
The Mongolian Sunflower is evocative, to say the least, but that's why you're drawn to it in the first place.
