Southern Seeds was founded in 2019 by Ryan and Kim Dorn and became Seed Therapy in 2025. The family business moved its operations to the Dallas, Texas, area in 2023. Drawing on generations of growing experience, the team focuses on dependable seeds, personal customer service, and helping gardeners succeed. Its work includes relationships with American farms and seed donations to schools and community gardens.

Create a pollinator paradise in the moist areas of your garden with Swamp Milkweed seeds. This beautiful North American native perennial is famous for its large clusters of intricate, vanilla-scented, rosy-pink flowers. It is an essential host plant for the monarch butterfly, providing the sole food source for their caterpillars, and its nectar-rich blooms are a magnet for a huge variety of bees and butterflies. Unlike many other milkweeds, this variety thrives in moist to wet soils, making it the perfect choice for rain gardens or planting along streams and ponds.
