Allium Millennium

Allium 'Millennium' is a striking ornamental onion, celebrated for its clump-forming habit and vibrant purple, globe-like flowers that bloom in summer. Its lush, strappy green foliage remains attractive throughout the growing season, making it a standout in borders or containers. This hardy perennial thrives in well-drained soil and full sun to light shade. In Melbourne, its cool winters and warm summers suit Allium 'Millennium' well, requiring moderate watering and protection from prolonged wet conditions. In Sydney, ensure good drainage and provide water during dry periods to cope with humid summers. In Brisbane, its tolerance for heat makes it viable, but ensure some afternoon shade and consistent moisture during the hotter months. Deadhead spent blooms to encourage prolonged flowering and cut back foliage in late autumn for fresh spring growth.
