They grow! Questionable decisions and zero experience!
Mammoth sunflower I would consider myself a “pre-K level” gardener. I know plants need sun, soil, and water, and that’s about where my gardening knowledge ends. Last year, none of the sunflower seeds I planted outdoors germinated. In hindsight, birds and squirrels probably ate them. This year I saw someone online germinate sunflower seeds in wet paper towels inside a plastic bag and thought, “Surely I can do that.” So I started these Mammoth sunflower seeds indoors in March. Then I realized it was still too cold to plant them outside. A quick Google search told me sunflowers don’t like their roots disturbed, so I moved them into peat pots. Because I was convinced most of them would die, I planted 2–3 seedlings per pot. Somehow, they all survived. By the time I planted them outside at the end of April, I still had no real plan. I watered them, left them alone, and let nature do its thing. Two eventually died—not because of the seeds, but because I accidentally tied them to a support with metal wire and the growing stems cut themselves against it. (Again: pre-K gardener.) The rest absolutely took off. The tallest are now over 6 feet tall, and for reference, my SUV is about 75 inches tall. If you’re wondering whether Mammoth sunflowers actually grow as advertised, I can personally confirm they do. If someone with virtually no gardening experience can get these seeds to thrive after a series of questionable decisions, I’d say they’re pretty forgiving and beginner-friendly.
