Say thank you with a gift that reaches for the sky! The Bentley Seed Co. "Thank You for Helping Us Grow" Mammoth Sunflower Mix Seed Packet pairs an artistic botanical design with premium giant sunflower seeds.

Each packet contains 1 gram of seed. Once sown in a sunny garden spot, these seeds quickly grow into towering 6 to 9-foot plants crowned with golden blooms. They produce abundant, healthy seeds that can be harvested for eating or left on the stalk to attract wild birds and pollinators.

  • When to Sow: Direct sow seeds outdoors into prepared soil after all danger of frost has passed in the spring.
  • Planting Depth & Spacing: Choose a location with full sun exposure. Cover seeds 1/2 inch deep in loose soil and pack down firmly.
  • Thinning: When seedlings reach 3 inches tall, thin them to 18 to 24 inches apart to allow proper stalk development.
  • Watering & Care: Water regularly during dry periods. Full sun is best for achieving maximum plant height and bloom size.
  • Educators & School Staff: Pair with a gardening trowel, watering can, or small plant pot for Teacher Appreciation Week, tutors, or end-of-year gifts.
  • Mentors & Coaches: Express gratitude to mentors, advisors, sports coaches, or scout leaders who have supported personal or professional growth.
  • Employee & Workplace Appreciation: Perfect for Administrative Professionals Day, team milestones, or company-wide staff thank-you gifts.
  • Volunteers & Non-Profits: Hand out at community events, garden clubs, or charity fundraisers to show appreciation to dedicated volunteers.
  • Family & Friends: Give to parents, grandparents, or supportive friends as a lasting token of thanks.
