By growing food sources for monarch butterflies (flower nectar) and caterpillars (milkweed), you can help declining populations of monarchs while enjoying a beautiful and iconic visitor to your garden.

Milkweed plants are an essential part of a monarch-friendly garden since monarch caterpillars feed exclusively on milkweed plants. There are two native milkweed plants in New Brunswick: Common Milkweed and Swamp Milkweed

Common Milkweed

This Milkweed species is for larger areas where spreading plants are less of a concern. As it spreads by the rhizomes (roots), it can colonize an area quickly.

Swamp Milkweed

If you want something more well-behaved in a small garden, this Milkweed will stay where you plant it. The leaves are narrower and the flower is a brighter shade of pink.
