Description:
Bright yellow flowers bloom from July to August on Senna hebecarpa, also known as Wild Senna. The plant thrives in well-drained soils with a pH range of 6.0 to 7.0 and has a medium tolerance to drought. Although it’s not a preferred choice for deer, it does have some deer resistance. Its bushy growth reaches a height of 3 to 6 feet, and it spreads to a width of 3 to 4 feet, making it suitable for the back of borders or naturalized areas. The vibrant yellow flowers attract various pollinators such as butterflies and bees, and it serves as a host plant for certain caterpillars, including Sulphur Butterflies. Senna hebecarpa is a perennial shrub that’s hardy in USDA zones 4 through 8. Its low salt tolerance makes it less suitable for areas with significant salt exposure, such as coastal regions or places where road salt is common. Ideal for meadows, gardens, or open woods, Wild Senna’s medium growth rate and native status make it a valuable addition to many landscapes.
