Helianthus angustifolius

Swamp Sunflower makes an impression with its brilliant yellow disc flowers. These bright flowers make an appearance in summer and display until the first frost. As flowers are pollinated, they give way to seeds that are a source of food for songbirds through late fall. Since Swamp Sunflower can grow to eight feet tall, or even taller in some cases, staking can prevent the plant from falling over in windy conditions. It needs room to grow and can quickly overwhelm small garden spaces. This perennial will do well in areas needing to be filled in with a splash of color towards the end of the growing season. Although it is a sunflower, it can handle and even thrive in part sun. Due to its moderate salt resistance, Swamp Sunflower can withstand being planted near roads. Deer resistance has been reported, but protecting small plants is advised while they get established. In addition to providing nectar for pollinators, this plant is a host for Silvery Checkerspot caterpillars.
