Perennial Exchange

Gardeners love to share! The EHS’s semi-annual Perennial Exchange is a great opportunity to find new homes for your extra plants, exchange them for new ones, and buy locally hardy plants at reasonable prices. You can donate and buy garden tools, too.

This event is held twice a year—each spring just as you are getting started and may have extra plants, and during fall clean-up when you may be dividing perennials or have seeds to share.


Here’s how it works:

For every plant you bring, you get one credit. During the exchange, you can trade your credits for plants that someone else brought. After the exchange portion of the event, remaining plants are sold for very reasonable prices. There are vendor and display tables to browse and the popular Garden Tools table, where EHS members and others can donate gently used unwanted garden equipment to be sold to benefit EHS.


Why participate?

  • To get new plants that grow well locally
  • To share your excess plants with others
  • To meet fellow gardeners
  • To have a good time

Prepare before you come.

Guidelines for preparing your plants:

  • Please pot healthy plants in individual, sturdy containers (not paper or plastic bags, please). Bulk, bare root stock (such as iris) is permitted but must be identified as to the quantity of tubers, bulbs, or corms, as well as the labeling requirements listed below.
  • Plants must be labeled. Please identify plants by botanical name, if known, and common name. It’s very helpful if you can also indicate height, spread, bloom colour, location preference, and bloom time.


  • No guarantee is offered that there will be plant material available of equal value to your plants.
  • No credit is given for Chives or Goutweed.
  • We do not accept plants designated as noxious or prohibited noxious. Here is a partial list of Noxious and Prohibited Noxious plants in Alberta; for a complete list see the fact sheets at
