Swamp Sunflower

Helianthus angustifolius

Helianthus

Sunflower

The sunflower was once an emblem of the Inca Sun God. This well-loved genus is 150 species strong and includes not only sprightly garden plants but commercially important food and oil crops. Our easy-to-grow selections make great cut flowers and attract bees plus tolerate a wide range of soil conditions.

<i>Helianthus angustifolius</i>

A cheerful mop of clustered golden yellow daisies crest towering, 6 ft. tall valiant stems guised with leathery needle-like rich green leaves. One of the last perennial Sunflowers to bloom, this striking American native flaunts copious large flowers, each defined by nearly 15 sun-stained petals encompassing a purplish brown cone. Hard to miss, even from a distance, the Swamp Sunflower’s brilliant persona can grace the perennial border, stylized meadow or butterfly garden, where it grows well among Asters and Schizachyrium, wards off deer and relishes sunny moist niches, but acquiesces to other conditions.

Blooms September–October

Size: 6' 0" high x 2' 0" – 3' 0" wide.

Hardy to zone 5.
