About Late Horse Gentian

Late Horse Gentian, also known as Feverwort or Tinker's Weed, is a robust and architectural perennial that stands out in the summer landscape. It is closely related to Early Horse Gentian but is easily distinguished by its 'perfoliate' leaves, which are joined at the base to completely surround the central stem. Growing up to 4 feet tall, it produces intriguing dull red to brownish-purple flowers in early summer, which later develop into bright orange-yellow berries. This species is native to the central and eastern United States, favoring open woodlands, thickets, and rocky soils in full sun to partial shade. Its deep root system makes it exceptionally hardy and resistant to dry spells. Ecologically, it serves as an important nectar source for long-tongued bees and a food source for birds. It is a low-maintenance choice for gardeners looking to add unique textures and wildlife support to their landscape, thriving in a variety of well-drained soil types.
