A mounding shrub that grows 3-5 ft. high with a wider spread. In July, it produces huge (8-12in.) round heads of pure white blooms that remain attractive into September and can be cut for fresh or dried arrangements.

Its small scale and summer flowering make it a good choice for the mixed border. 'Annabelle' is most at home in partial shade and evenly moist but well-drained soil; she'll grow in full sun if moisture is ample. Because she flowers heavily on the current season's growth, most gardeners cut the stems to the ground in late winter. New shoots emerge from the base and bloom the same summer. Not a good choice for gardeners in the desert Southwest.

Bareroot and potted.
