With huge flowers (often 10 or 12″ inches across) these garden giants are hybrids developed for seed production (Sunflower oil, bird seed, etc.) But we’ve had so many requests for them, we now have them available for meadow planting. Remember, these are the ones that grow from 8 to a whopping 12 ft. 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. Enjoy!
