2026 Sunflowers Forever Stamps — Floral Collection, First-Class Postage

The plant

The sunflower's botanical name, Helianthus annuus, comes straight from the Greek: helios for sun, anthus for flower. North America hosts more than 50 distinct annual and perennial sunflower species beyond the common one. Like the alpine buttercup and the Arctic poppy, young plants track the sun east to west across the day; the habit fades as the stem stiffens with maturity.

Why gardeners and pollinators both want them

Sunflowers supply reliable nectar and seed for birds, bees and butterflies. They also earn their place agriculturally — drought tolerant, useful for natural pest control, and equipped with deep taproots that improve the soil they grow in. They put up with dry spells and poor ground, but there is no getting around the name: they need full sun.

The stamp art

Four stylized blooms in yellow, gold and brown, stems and leaves in greens, on a pale yellow ground. Illustrator Nancy Stahl worked from photographic references, sketched in ink, then colored the drawing in a vector application. She describes aiming for approachable, interesting readings of familiar subjects — and says she was pulled in by the underside of the bloom, where the stem finishes in an almost petal-like double ring of small green leaves, and by the Fibonacci spiral of the seed head, which she found mesmerizing once she started looking.
