Parthenium integrifolium 25 Seeds – Wild Quinine Native Prairie Wildflower White Pollinator Perennial

Parthenium integrifolium, commonly known as Wild Quinine, is a native North American perennial wildflower that brings long-lasting white blooms to prairies, meadows, and pollinator gardens. Its sturdy stems and coarse, aromatic foliage form a clump that produces flat-topped clusters of small white flowers from early summer into fall. The flowers resemble tiny pearls and are highly attractive to bees, butterflies, and other beneficial insects.

Wild Quinine is valued for its drought tolerance, adaptability to poor soils, and ability to thrive in full sun. It works well in native plantings, rain gardens, wildflower meadows, and perennial borders where a tall, architectural accent is desired. The seeds offered here are ideal for gardeners looking to establish this underused native species from scratch.

Planting & Care

Wild Quinine seeds benefit from cold moist stratification to improve germination. For best results, sow seeds in late fall or winter outdoors, or stratify them in the refrigerator for 30 to 60 days before starting indoors. Surface sow or lightly cover the seeds, as they require light to germinate. Keep the soil consistently moist until seedlings emerge, which may take several weeks. Once seedlings have a few sets of true leaves, thin or transplant them to their final spacing.

Choose a sunny location with well-drained soil. Water regularly during the first growing season to help plants establish a deep root system. After establishment, Wild Quinine is quite drought tolerant and needs little supplemental water except during extended dry periods. Deadhead spent flowers to encourage additional blooms, or leave seed heads standing for winter interest and wildlife. Divide clumps every few years in early spring if they become overcrowded.
