Astilbe 'Montgomery' (Astilbe japonica) features dense, dark magenta red flower plumes borne on upright, dark red stems. Quite showy, they rise gracefully in early to midsummer above an attractive mound of fern-like deep green, glossy foliage.
Astilbes are one of the easiest perennial flowers to grow. They have long-blooming, plume-like flowers in soft shades of white, pink, and red, and the flowers are held on tall, stiff stalks above the airy foliage. Virtually pest-free, they can light up the shade garden or soften a sunny spot, and they are very low maintenance. Astilbe plants are also known as false spiraea, false goat's beard, and meadowsweet. There are several species and cultivars within the Astilbe genus, with variety in the flower plumes. Most of the popularly sold Astilbes are hybrids resulting from crosses among the species.
