Summary
Tetramerium nervosum, commonly known as Hairy Fournwort, is a deciduous perennial subshrub or herb that is native to a variety of habitats including grasslands, arroyos, and riparian zones in the Americas. It typically grows to a height of 0.5-1 feet (0.2-0.3 meters) and a width of 0.3-0.8 feet (0.09-0.2 meters). The plant has a bushy habit with green, hairy leaves and produces small, tubular yellow and white flowers that are attractive to pollinators during its blooming season in the spring, summer, and fall.
Hairy Fournwort is appreciated for its extended flowering period and its adaptability to different garden settings. It is often used in border plantings, rock gardens, and as a ground cover due to its low stature and spreading habit. This plant is relatively low-maintenance, requiring moderate watering and thriving in a range of soil types with medium drainage. It prefers full sun to part shade, which makes it versatile for various garden designs. While not commonly reported to have significant disease or pest issues, it can be susceptible to root rot in overly wet conditions.CC BY-SA 4.0
