5 Seeds Cassia marilandica Wild Senna Hardy Perennial
Cassia marilandica, commonly called wild senna, is a hardy perennial native to eastern North America, valued for its tall, shrub-like growth and bright golden-yellow blooms that appear in mid to late summer. Its feathery, pinnate foliage and nectar-rich flowers make it a striking addition to meadows, pollinator gardens, and naturalized borders.
This versatile perennial works well at the back of a border or in a rain garden, where its tolerance for varied moisture levels is appreciated. The bold foliage and late-season flowers extend color into late summer. Grow it alongside other native perennials for a layered, wildlife-friendly planting.
