Growing native plants and trees from carefully sourced seed is one of our main activities in supporting the Mayor's Monarch Pledge. It is also one way to be good stewards of nature.

Native plants are important host plants for local pollinators. For example, milkweeds are the only plants that a Monarch butterfly will lay her eggs on because these are the only plants that can feed the Monarch caterpillars.

Native plants also provide habitat for many species that they have co-evolved with for thousands of years.

With native pollinator populations declining due to habitat loss, pesticide use and climate change, one thing we can do to support them is by planting more native species as viable habitat for them. Together we can make a difference.

Keep an eye out on our Events page and social media, for information about our plant sales and seed exchanges!
