How to Grow and Care for Common mare's-tail

Common mare's-tail is distinguished by its rigid upright stems, which stand approximately 6 to 12 inches (15 to 30 cm) tall, and are enveloped by whorls of slender, hair-like leaves that extend outwards, resembling a bottle brush. These leaves arrange themselves horizontally around the stem, creating a distinctive radial pattern. Although present, the plant’s small white flowers that bloom in the summer are inconspicuous to the naked eye. Common mare's-tail is robust, thriving in full sun to part shade and can withstand cold temperatures down to USDA Zone 4. It propagates with ease via divisions or stem cuttings and is well-suited for aquatic environments, either marginally positioned in ponds or fully submerged in aquariums.
