  • circleLife cycle

    Astilbe 'Bonn', commonly known as False Spirea or False Goat's Beard, begins life as a perennial rhizome that sprouts in early spring. Its foliage emerges first, developing into attractive, fern-like leaves. By late spring to early summer, tall, plume-like flower stalks appear, displaying dense panicles of tiny, vivid pink flowers that attract pollinators and provide garden interest. After blooming, the flowers may fade to a brownish color, and if left on the plant, will provide structural interest and can be a source of seeds for propagation. As fall approaches, the foliage typically turns yellowish-bronze and eventually dies back with the onset of winter. The plant then enters dormancy, with the underground rhizome surviving the cold to regenerate the next spring, continuing its perennial cycle.

      Spring to Summer

    • The most popular method of propagating Astilbe 'Bonn', commonly referred to as False Goat's Beard or False Spirea, is by division. The ideal time to divide these perennials is in the spring or fall when the plant is not in active growth. To propagate by division, carefully dig up the plant ensuring you get a good amount of the root system. Gently separate the clumps into smaller sections, each with several shoots and a portion of the root system attached. Once divided, the sections can be replanted at the same depth they were growing at previously, spacing them about 18 to 24 inches (approximately 45 to 60 centimeters) apart to allow for adequate growth. Water the new divisions thoroughly after planting to help establish them. This method of division helps rejuvenate older plants while increasing your garden's stock.
