If you need a slow-growing grass that won’t overtake your garden, plant prairie dropseed! It will serve as a nice groundcover for hot and dry areas and has a unique fragrance that resembles coriander. It looks beautiful in rock gardens and will help accentuate your other perennials. This grass is easy to grow and it will tolerate a variety of soils, including dry rocky soil and heavy clays. Prairie dropseed will drop its mature seeds on the ground in fall but won’t easily self-seed. The grass is deer tolerant. Prairie dropseed hardiness zone is 3-9.
