Wetsel Seed™ Russian Mammoth Sunflowers

- 1/2lb

This fast-growing gigantic flower produces an immense golden blossom 8-14 inches across, that is filled with sunflower seeds. These easy to grow plants thrive in poor soil with little moisture and make interesting temporary screens, backgrounds and hedges. The large, tasty seeds attract wild birds and make valuable poultry food.
