- Rachel C.Verified ReviewerRated 5 out of 5 stars7/17/26Incredible heights, vigorous in California's Central Valley
I grew these and Mammoths this year. The mammoths were from another brand. These outpaced the mammoths by a country mile and had excellent germination rates. They also got taller than my Mammoths. If you're in hot and dry climate with clay soil, give these a go! My tallest so far bloomed at 8'. I thought one was stunted until I saw it had grown to 5', which is in the range of the package.

We're so happy to hear about your incredible experience with the Lemon Queen Sunflower Seeds! It's awesome that they outpaced the mammoths by a country mile - that's such a testament to how vigorous and reliable these beauties really are! And an 8-footer bloomer? That's absolutely amazing! We love that even your "stunted" one hit 5 feet, which just shows how consistently strong this variety performs! Your experience in California's Central Valley with that hot, dry climate and clay soil is super valuable feedback - it's so cool that the Lemon Queens thrived in those challenging conditions and delivered such fantastic germination rates! There's nothing better than sunflowers that exceed expectations and prove they can handle tough growing situations while still reaching incredible heights! Thanks for sharing your Lemon Queen growing success with us! Keep on growing 🌻️
