Grow a spectacular native wildflower with Helianthus angustifolius, commonly known as Swamp Sunflower. This stunning perennial sunflower is known for its tall upright stems, narrow leaves, and masses of bright yellow daisy-like flowers that bloom in late summer and fall when many other plants have finished flowering.
Swamp Sunflower is an outstanding choice for pollinator gardens, native plantings, rain gardens, meadows, and naturalized landscapes. It is especially valuable to bees, butterflies, and migrating pollinators, providing abundant nectar and pollen late in the season. Despite its name, it is adaptable and thrives in both moist soils and average garden conditions once established.
You will receive:
✔️ 200 fresh, viable seeds
✔️ Open-pollinated, native species
✔️ Carefully packaged for successful sowing
