A perennial plant with an extensive creeping root system, with reproduction from seeds. Plants mature at anywhere from 4 to 18 inches in height, adapting to conditions where they are mowed frequently by producing lateral stems and a more spreading habit. New growth may appear from these roots. Flowers and seed production occur in early to mid summer.
Extensive horizontal roots can make control difficult, and if a herbicide is to be used plants should be allowed to produce adequate foliage first. A systemic herbicide is needed to kill the entire plant and roots, and a pre-emergent herbicide may be effective on the seeds.
