Mammoth Sunflower Seeds Non-GMO
Giant heirloom sunflower with enormous blooms, up to 1 ft. across. The large yellow flowers with brown centers top plants 9-12 ft. tall and yield heavy loads of seeds. Fast and easy to grow. Natural Seed. Sunflowers attract butterflies and birds. They are easy to grow. Great for kids garden. Mammoth sunflowers are great for creating a tall annual hedge or screen.
Sow in the spring after the last average frost date. When around 3" tall, seedlings should be thinned to 2 ft. apart. Edible seeds attract birds and make great snacks. Watering every day will help them to grow faster. They tend to germinate 5-12 days after planting. To save seeds, cut the stem beneath flower heads when the backs of the flower heads turn yellow. Hang upside down and let dry in a cool, dry place for about a month. Cover with netting or a paper sack with holes to keep seeds from falling.
