Summary

Calycanthus floridus, commonly known as Eastern Sweetshrub, Carolina Allspice, or Spice Bush, is a deciduous shrub native to the understory of forests and along stream banks in the eastern United States. It typically grows to a height of 6 to 9 feet (2 to 3 meters) with a similar spread. The shrub is notable for its dark red to brownish-purple flowers, which bloom in late spring to early summer and emit a fruity, spicy fragrance. The flowers are somewhat showy, attracting attention with their unusual, magnolia-like appearance. The plant’s leaves are dark green with a paler underside, ovate or elliptical, and grow to about 6 inches in length. The bark has been historically used as a cinnamon substitute, and the petals are used in tea-making, though caution is advised due to the presence of potentially harmful alkaloids.

Eastern Sweetshrub is valued for its fragrant flowers and is used in horticulture for border planting, as a specimen plant, or in naturalized areas. It is adaptable to a range of soil types, provided they are well-drained, and it thrives in full sun to part shade. While generally disease-resistant, it is susceptible to crown gall caused by Agrobacterium tumefaciens. The plant is recognized for its ecological role as a pollinator plant, especially for beetles. It is not considered invasive and is relatively low-maintenance, making it a suitable choice for gardeners seeking a unique and aromatic addition to their landscapes.CC BY-SA 4.0
