The Genus Astilbe is a group of perennial flowering plants that are native to Asia and North America. Commonly referred to as false spirea, Astilbe is revered for its attractive and colorful plumes of flowers, which range in color from white to deep red. Some popular synonyms for the Genus Astilbe include mountain spiraea, silver-rod, and goat's beard. Additionally, different cultivars of Astilbe are often referred to by their specific names rather than the general Genus term, such as Astilbe chinensis, Astilbe japonica, and Astilbe simplicifolia. These plants are widely used in gardens and landscaping due to their hardiness and versatility, making them a popular choice for both residential and commercial properties.
