Rudbeckia ‘Prairie Sun’ Seeds

Rudbeckia ‘Prairie Sun’ (Rudbeckia hirta). Recognized worldwide for its outstanding garden performance, this prestigious All-America Selections and Fleuroselect Gold Medal winner stands out from classic black-eyed Susans with its striking, soft lime-green central cones framed by magnificent 12–15cm two-tone petals.

Each large bloom features bright golden-yellow petals tipped with soft primrose-yellow ends, creating a glowing sunburst effect across the plant. Built on sturdy, heat-tolerant stems that rarely require staking, 'Prairie Sun' provides a long-lasting burst of color from mid-summer straight through to the first hard frost of autumn. It is a dual-purpose powerhouse in the garden—serving as a high-performing cut flower for long-lasting vase arrangements, while acting as a vital pollinator magnet for native bees, butterflies, and beneficial garden insects.

• Gardener’s Tip: To encourage continuous flowering all season, deadhead spent blossoms regularly.

At the end of the season, leave a few final bloom heads to dry on the plant—their seed heads provide valuable late-autumn food for wild birds.
