The 2015 Perennial Plant of the Year™

Each year, members of the Perennial Plant Association from all across North America vote on their choice for Perennial Plant of the Year™.  PPA members vote for the Perennial Plant of the Year™ each summer. In addition to the vote, each member may also nominate up to two plants for future consideration. The Perennial Plant of the Year™ committee reviews the nominated perennials (more than 400 different perennials are often nominated each year), selecting 3 or 4 perennials to be placed on the ballot. Nominations generally need to satisfy the following criteria:

  • Suitability for a wide range of climatic conditions
  • Low-maintenance requirements
  • Relative pest- and disease-resistance
  • Ready availability in the year of promotion
  • Multiple seasons of ornamental interest

Geranium cantabrigiense ‘Biokovo’ is a low-growing hybrid, found originally in the mountains of Eastern Europe. Plants form a low, spreading mat of fragrant dark green leaves, bearing clusters of white flowers, with a tinge of soft pink. The very long flowering period makes it especially useful as a low groundcover or edging plant and in tubs or mixed containers. Fairly drought tolerant, once established. Easily divided in spring or early fall. Evergreen.
