Pleurisy Root, also known as Butterfly Weed, is a resilient herbaceous perennial native to the American prairies. This striking plant produces bright orange to yellow—sometimes nearly red—blooms on upright stems reaching up to 3 feet tall. It thrives in full sun and adapts well to garden soil or low-fertility conditions, making it suited to naturalized plantings, prairie gardens, and pollinator habitats. A favorite among Monarch butterflies, Pleurisy Root serves as both a nectar source and a vital host plant.

Label the row with the sowing date so actual performance can inform future plantings. Before sowing Pleurisy Root (Butterfly Weed), review the packet alongside the current product details and note any range in temperature, germination, or maturity. Ranges reflect biological and seasonal variation rather than a fixed promise. Label each planting with its date and location, then compare emergence, growth, and harvest with local weather. This record is useful for succession plantings and for deciding whether the crop fits better into an earlier or later seasonal window. Explore related options in our full collection of herb seeds.
