100 Swamp Sunflower Seeds Perennial Native and 50 similar items

SWAMP SUNFLOWER seeds. Easy to grow, tough as nails true sunflower. Native to North American coastal areas, they can be found growing around a salt marsh or in a roadside ditch. They thrive in almost all conditions. These don't spread aggressively like some sunflowers, but rather form clumps that can last for years. This is a tall, good-looking plant that blooms profusely in fall, when most perennials are ready for a long nap. 3" bright yellow daisy like flowers, with a black center, they look like a Black-Eyed Susan. They make long lasting cut flowers. Also, they are a host plant for the Checker Spot Butterfly and a fall/winter seed source for Cardinals, Orioles, Thrushes and many others.100+ Seeds per order. Thank You! Some American Native Wildflower seeds need to go through a cold winter to germinate. This plant is one of them. They do this so the seed won’t sprout in fall, only to have the seedling not make it through a cold winter. I have stratified these seeds to simulate a cold winter(stratification) This raises the germination rate considerably. Thanks for looking!! Helianthus angustifolius. Perennial. Full sun.
