Companion planting involves selecting plants that complement each other in a way that benefits both. Here are some reasons why the plants listed in the previous table are good companions for the popular ornamental plants in Canadian landscapes:

Plants with similar light and moisture requirements: Companion plants that have similar light and moisture requirements are likely to thrive in the same conditions. For example, hostas and ferns are often planted together because they both prefer shady conditions and moist soil.

Nitrogen Fixers: Some plants, such as clover and beans, are able to fix nitrogen from the air and deposit it in the soil. This nitrogen boost can benefit nearby plants that require a lot of nitrogen, such as roses.

Attracting pollinators: Companion plants can attract beneficial insects such as bees, butterflies, and other pollinators to your garden. For example, planting echinacea and black-eyed susan together can attract pollinators to your garden and improve the health of both plants.

Deterring pests: Companion plants can help to deter pests and diseases from affecting other plants in the garden. For example, planting marigolds near vegetables can help to deter pests such as aphids and other insects that can damage vegetables.

Covering bare spots: Companion plants can help to fill in bare spots in the garden and create a lush, full look. For example, planting low-growing perennials such as catmint near peonies can help to fill in bare spots and create a more attractive garden.

Adding height: Companion plants can also be used to add height to the garden and create visual interest. For example, planting tall perennials such as iris near shorter perennials such as Shasta daisy can help to add height to the garden and create a more visually appealing landscape.

In conclusion, companion planting is an important aspect of garden design that can help to create a more beautiful and functional garden.
