Sunflower Tall Single Stem Mammoth Grey Stripe 25 Non-GMO, Heirloom Seeds
Tall Single. With huge flowers (often 10 to 12 inches across) these garden giants are developed for seed production (Sunflower oil, bird seed, etc.) Remember, these are the ones that grow from 8 to a whopping 12 feet tall, so unless you're planting them alone, scatter them throughout your meadow, or use them as a background screen. Kids love watching them grow so fast and so tall, and of course, they're magnets for songbirds.
Special Note! These HAVE to be direct sown--as do most sunflowers. They do not do well transplanted. You need to space them at least 12 to 18 inches apart. Blooms in about 110 days. Germination rate about 70% or better.
Our Non-GMO seeds are sustainable. Our packaging is environmentally friendly, climate friendly, reusable, and recyclable.

This is an heirloom seed, meaning it has been passed down from generation to generation for at least 75 years. As a rule, heirloom seeds taste better and will grow the same year after year.
These are also open pollinated meaning they will reproduce themselves. While all heirlooms are open pollinated not all open pollinated seeds are heirlooms.
Companion planting is planting seed varieties near each other to benefit one or more of the plants. Some plants benefit each other by attracting beneficial insects, keeping away unwanted bugs. Others aid in pollination. Some plants have working relationships with each other and others have antagonistic (hostile) relationships.
