Cardinal Chinese Astilbe



Cardinal Chinese Astilbe (Astilbe chinensis 'Cardinal')
Cardinal Chinese Astilbe (Astilbe chinensis 'Cardinal') is a bold, late-blooming perennial valued for its vivid red flower plumes and rugged adaptability to challenging garden conditions. With its strong texture, upright form, and reliable performance in shade or sun, this cultivar brings lasting color and structure to borders and woodland plantings.
Distinctive Features
