Welcome to Perennial Plant of the Year

This page features the plants that have been designated the Perennial Plant of the Year (PPOY). The PPOY are display in chronological order from the current year’s designated plant to previously designate plants. The plants are selected by the Perennial Plant of the Year Committee. Each year, the committee considers many plants. Committee members are passionate about their plant nominations and ardent debates about which plant deserves the designation occur.

To be selected as Perennial Plant of the Year, the plant must meet all the criteria:

  • suitable and reliable in Calgary growing conditions
  • not overused
  • readily available in garden centres
  • reasonably affordable to purchase

The Perennial Plant of the Year is announced in April, and usually displayed at the Society’s Garden Show.
