'Serendipity' Ornamental Onion (Allium hybrid)

Our perennials are currently going dormant. The foliage and blooms begin to brown and die back. We provide a hard trim in the greenhouse to support this process. During dormancy, plants go inactive to conserve their energy for the next growing season. This happens naturally as seasons change!

'Serendipity' Ornamental Onion (Allium) boasts globe-like, rosy-purple flowers mid to late summer that top attractive blue foliage. The upright habit works as a thriller in containers and the landscape. Alliums are charming plants for the rock or herb garden. When the foliage is bruised, it smells like onions since they are in the onion family. Butterflies and honeybees adore the flowers' sweet nectar but deer and rabbits steer clear of this perennial beauty.

  • 15-20 inches tall and 10-15 inches wide at maturity
  • Grow in zones 4-8
  • Plant in part to full sun (4+ hours daily)

Our perennial plants are entering their natural dormancy phase. As part of this process, foliage and blooms are browning and dying back—this is completely normal! We give the plants a hard trim in our greenhouse to support them as they conserve energy for the next growing season. Rest assured, your perennials will wake up and thrive again when it's time in your growing zone. Dormancy is how they prepare for a healthy, vibrant comeback as the seasons change!

Care: Trim stems after it has finished flowering if desired. Fertilize with Proven Winners Continuous Release Plant Food in spring.
