Matchweed is a herbaceous plant that is known for its slender, slightly curved stem and small, white flowers. Some synonyms for matchweed include Crotonopsis linearis, Crotonopsis elliptica, and Euphorbia linearis. Though these names may be less common, they each describe the same slender, wiry plant with tiny, delicate flowers. Other related plants in the Euphorbia family may have similar appearances and growth habits, and may also be referred to as matchweed in some regions. Botanical names may differ depending on location, but regardless of the name, matchweed is valued for its low-maintenance and pest-resistant qualities, making it an excellent addition to any garden or landscape.
