Want to eat more locally grown foods? Reap the positive benefits of gardening? Grow edible perennials!

Whether you’re a seasoned gardener or just starting out, you’ll elevate your culinary experiences by adding perennial herbs, flowers, vegetables, fruits and nuts you can harvest year after year. It’s good for your wallet, wellbeing and the planet.

What’s a perennial?

Annuals (e.g., peas), complete their life cycle in a single growing season. Biennials (e.g., leeks) take two years to complete their life cycle. Perennials live for more than two years. The best time to plant them is spring and fall. They grow and bloom during the spring and summer, die back in the fall and winter and then return from their rootstock the following spring.

Perennials are great because they:

  • Keep coming back and can be left all winter.
  • Withstand pests better than annuals.
  • Build and improve soil quality.
  • Don’t need tilling, leaving mycelial culture (mushrooms and other fungi) and soil structure intact.
  • Increase aeration and water absorption.
  • Create compost, add to topsoil and bring up nutrients from deep down when dropped leaves die back each year.
  • Are “edimentals” (edible ornamentals) — delicious and beautiful!
  • Are often long-lived — e.g., asparagus can live up to 40 years!

Support pollinators by planting native edible perennials

Try to plant edible perennials native to your ecoregion. They will be better adapted to local conditions and support pollinators’ important work.

Native plants evolved over millennia along with other plants species, animals, fungi and bacteria in the presence of native soil and climatic conditions. Pollinators evolved to depend on native plants in their specific regions for food and habitat.

Help support the health and diversity of local ecosystems while creating beautiful, beneficial pollinator habitat by planting native edible perennials (and wildflowers, trees and shrubs!) for your ecoregion.

Perennials marked with an asterisk (*) below are native, or have a species native, to a region in Canada. Prioritize plants native to your ecoregion, if possible.

How to source native seeds and plants

Whether you’re creating a vegetable garden, pollinator paradise, wild bee sanctuary or butterfly garden, there are many creative — often free — ways to source native seeds and plants.

EXPLORE EIGHT DIFFERENT WAYS

  • Sweet potato (Ipomoea batatas)
  • Rhubarb (Rheum rhabarbarum)*
