Woodland Sunflower is a wildflower species that grows about 1.5 m in height. This plant may also be known by the common name Paleleaf Sunflower. The leaves are green, narrow, have slightly rounded bases, and have entire margins. The arrangement is mostly opposite but may be alternate on the higher branches. These sunflowers have a smooth stem which may have a whitish bloom. The flowers are bright yellow coloured, have 8-12 ray petals, have numerous disk florets in the center, and bloom between July and September. The flowers are beneficial to pollinator species, like bees and butterflies. The seeds are also beneficial to wildlife species, like birds and small mammals. This plant is easy to grow and is low maintenance. It can spread quickly through seeds and rhizomes to produce small colonies.

Woodland Sunflower grows best in normal to dry conditions with full or partial sun exposure. It prefers well-drained loam or sand soil types. This wildflower can be naturally found in dry open forests, forest edges, in fields or meadows, and along roadsides.
