Swamp Sunflower

Helianthus

Sunflower

The sunflower was once an emblem of the Sun God of the Incas. 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 tolerate a wide range of garden soils, attract bees, and make great cut flowers.

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.

Helianthus 'Sheila's Sunshine', Persicaria 'Summer Dance', and Selinum wallichianum

Helianthus ‘Sheila’s Sunshine - P-0461

The sunflower was once an emblem of the Sun God of the Incas. Our sunflowers tolerate a wide range of garden soils, attract bees, and make great cut flowers. Blooms early August – October.

Persicaria ‘Summer Dance’ - P-1312

With foliage that’s close to lime-green, and spiky floral tails that approach the scarlet spectrum of rosy pink, this slow spreading perennial is sure to please. Happiest in semishade with ample moisture. Blooms August–November.

Selinum wallichianum - P-1406

This refined Himalayan beauty happens to be one of our favorite perennial umbellifers. With untold elegance, infinitely divided leaves craft a delicate, lacelike transparency. The compact yet airy green canopy is framed by distinctive, purple-infused branching stems that elevate a charming, late season display of white flattened umbels.

Subduing the riotous array of summertime blooms, it seldom needs staking, and appreciates a well draining moist niche. Blooms June–August.
