‘High Noon’ Long-Lasting Sunflower Seeds

High Noon holds the summer light for weeks. Dense branches line its central stalk with clusters of 4–5-inch flowers, their golden petals warming toward orange around chocolate-brown centers.

The tall 6–8-foot plants create an easy screen and provide a steady run of stems for cutting. Pollinators find the open centers readily, and later the seed heads offer another reason to leave a few blooms in the garden.
