Red sun sunflowers create vibrant large blooms throughout the year. They grow quickly and can get up to eight feet tall. They don’t take long to germinate and are easy to care for. Each pack comes with 20 seeds and basic instructions for germination. I’m a USA seller which means faster shipping times as well as higher quality seeds. A vast majority of my seeds either come from my garden, from my neighborhood or in the local area. If not, I’ve acquired them on trips around the country. I’ve tested and grown many of these myself. I’m always here for assistance with germination and growing. Your success is my success!
