Why the stamp was issued: This stamp pictures sunflowers, one of America’s most recognizable native plants.
About the stamp design: Nancy Stahl created the four stylized sunflowers featured on the stamp. Working from photographs, she sketched the flowers before adding colors digitally. Stahl’s work has been showcased on many stamps in the past.
First Day City: The dedication ceremony for this stamp was held at the Garfield-Perry Stamp Club’s 136th annual March Party in Strongsville, Ohio.
History the stamp represents: Named for its sun-like face, sunflowers are part of the genus Helianthus, comprising over 70 species and hundreds of cultivars. Colors range from pale cream and soft orange to deep burgundy and rich chocolate-red. Their size varies too—from the compact, fluffy-petaled Teddy Bear, barely two feet tall, to the towering Russian Mammoth, which can reach twelve feet with blooms wider than a dinner plate.
That cheerful face isn’t a single flower. It’s a flower head—a tightly packed community of hundreds of tiny individual blooms. The bright outer petals belong to ray flowers. The center is composed of disk flowers, each a complete blossom, opening in sequence from the outer edge inward, like a slow, circular countdown.
That center holds one more secret. The disk flowers spiral outward in the Fibonacci sequence — the same pattern found in nautilus shells and galaxies. The spirals turn at 137.5 degrees, packing every seed into the most efficient arrangement nature could devise. It works so well that engineers still study it today.
The belief that sunflowers follow the sun is part myth. Mature plants permanently face east - the sun’s warmth draws more pollinators earlier in the day. Young sunflowers do follow the sun, tilting east to west in a process called heliotropism. This inspired the Spanish and French names, both meaning “turns with the sun.”
