The Evergreen Native Plant Database is a great tool for learning about and choosing native plants. If you really want to be sure a plant is native to Nova Scotia and learn about its natural habitat, consult Roland’s tome, The Flora of Nova Scotia, available online here: Part 1 and Part 2.

It can be a challenge to find sources of native plants, and even as the garden was being planned, some nurseries were closing. Here’s a list of nurseries in Nova Scotia that supply native plants suitable for rain gardens.
