Cultural Notes
    A.Filipendulina is low-maintenance, tough, drought resistant, and especially useful for dry, inhospitable landscapes and gardens. To prevent overcrowding and maintain vigorous growth (or to propagate), divide A. filipendulina every third or fourth year. Where space isn't a problem and the soil isn't particularly fertile, it can be left longer without division.

Design Uses
    Excellent feature plant for the summer border--as specimens toward the middle or rear of the border. Create a bold com- bination by planting A. filipendulina with Echinacea purpurea and Echinops ritro, or combineA. Filipendulina with E. ritro and Malva alcea 'Fastigiata' to anchor a border for mid- and late summer bloom.
    Achillea Flipendulina 'Gold Plate', with bright yellow flow- ers almost 6 inches across, grows up to 4 or 5 feet tall and is one of the most popular hybrids.
    The hybrid A.'Coronation Gold', with mustard yellow flowers, grows from 21/2 to 3 feet tall, is less likely to require staking, and will bloom well into summer if faded flowers are removed to prevent the formation of seeds.
