About This

  • Beautiful - Mammoth Sunflower (Helianthus var. 'Mammoth') seeds. These seeds grow crazy tall huge beautiful sunflowers with heights of 8-12 ft. The seeds are open pollinated and can be saved to plant year after year. Harvest and roast your own sunflower seeds. Minimum of 8g per packet (approximately 70 to 80 seeds).
  • Productive - Mammoth Sunflower germinates in 7-14 days when soil temps are 70-75°F. Plant 1” deep and space 3’ apart in an area with full sunlight. This variety will grow 8-12’ tall with a spread of 2-3’. Flowers will mature in 80-90 days, plant in USDA zones 3-9.
  • Pollinator and Bird Friendly - Bees love the nectar in sunflowers and will travel around helping pollinate your garden. Towards the end of the season, birds also love to come and eat the dried seeds.
  • Easy to Grow - Instructions included on each packet. Plus, we are available to answer all your questions. If these seeds don’t germinate, we will happily make it right for you.
