Astilbes are usually associated with the herbaceous border – 3 ft high plants bearing feathery plumes ofin summer. There are also a number of dainty miniatures which grow less than 1 ft tall – choose one if you have a small neat bed or a cool and damp spot in the rockery to fill. They bloom in midsummer when so many other alpines have passed their flowering season and their miniature ostrich plumes make a pleasant change from the usual flower form of rockery perennials. Remember, however, their need for moisture – they will -fail in dry conditions.
