Astilbe (False Goatsbeard)
Easy and tough perennials grown for their showy plumes of fluffy flowers that emerge in summer or early Autumn, held above decorative deep green foliage on firm wiry stems that don’t flop in wet weather. All Astilbes like moist soil, they are perfect on clay, poorly drained soils, bog gardens and on the margins of ponds. Full sun or partial shade
As a rough guide planting Astilbe as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage and 9-12 will make a weed supressing carpet very quickly.
