Our Mission

The Northwest Perennial Alliance (NPA) is an organization of ardent gardeners with a passionate devotion to herbaceous plants. Members comprise a wide range, professional to amateur, but all with the aim of furthering gardening in the Northwest.

NPA is organized primarily for educational purposes, which includes:

  • The advancement of knowledge and education of gardeners  through lectures, garden tours, the NPA Border at Bellevue Botanical Garden (BBG), literature and other educational programs
  • The advancement of the culture, study and availability of hardy herbaceous plants
  • The conservation of rare, old and lesser-known hardy herbaceous plants

What is a perennial?

The Northwest Perennial Alliance is often asked this question! Our organization was formed in 1984 by a group of passionate gardeners who wanted to promote the use of perennial plants to add to their mixed plantings of trees, shrubs, and annuals. They helped bring perennial plants to the attention of NW gardeners and growers, resulting in the expanded plant selection found today! 

The term ‘perennial’ describes plants that live more than two years, excluding trees, shrubs and bulbs. There are three commonly referred to types of perennial plants:

  • Herbaceous Perennials grow from their root stock in the spring, then die back to the ground in winter (Hosta)
  • Evergreen, or Non-herbaceous Perennials, do not die back in winter (Bergenia)
  • Sub-shrubs retain a woody structure in winter and regrow from that structure in spring (Hardy Fuchsia)

Perennial plants are popular with many gardeners due to their hardy nature, natural beauty, and reliable performance.
