Butterfly Milkweed is a Great Pollinator Plant

It took me several years to establish Butterfly Milkweed in my backyard habitat garden. I started with seeds and transplants purchased from nurseries. All failed. I finally succeeded with starting transplants from seeds. I used Milkweed/Butterfly Flower Seeds – $2.49
from Botanical Interests. (affiliate link).

What I learned is a method that works for me. I start perennials in containers and keep them in a pot for an entire season. The next spring I plant them out in the spot I want them to grow. Many perennials seem to need the first year to grow and establish roots without having to compete with other more vigorous or established plants.

The other plant whose name is like Butterfly Milkweed is Butterfly Bush. The Butterfly Milkweed is the plant to grow. It is the host plant of Monarch butterfly larva and indigenous to North America.

Butterfly Bush is an invasive plant species that gardeners across the United States. It may not be invasive in Canada. That could change as the climate and growing conditions warm in the coming years. The Butterfly Bush produces nectar but not nutritious pollen. So, its food value to insects is less than a plant that provides both nectar and pollen. If you have limited garden space a more useful plant would be better.
