Milkweeds for Monarchs

Milkweeds For Monarchs: The St. Louis Butterfly Project is an effort to create pollinator habitat in ways that foster the connection between people and nature

About the Initiative

STL_MonarchProjectLogoFINALOn Earth Day 2014, former Mayor Francis Slay launched Milkweeds for Monarchs: The St. Louis Butterfly Project to foster the connection between people and nature where they live, work, learn and play. 

Milkweeds for Monarchs (overview document herealigns with the City of St. Louis Urban Vitality & Ecology and Biophilic Cities efforts, and advances objectives in the City of St. Louis Sustainability Plan. The City led the effort in 2014 by establishing 50 monarch gardens; most of these gardens are located at fire houses and City parks. The community was challenged to plant an additional 200 monarch gardens to celebrate the City's 250th birthday. Gardens that were then registered appear on the Milkweeds for Monarchs Map. The urban program was expanded in 2015-16 to create 50 school monarch gardens, and then to create a St. Louis Riverfront Butterfly Byway - a collection of sites totaling a 30-acre pollinator pathway along the Mississippi Riverfront. The Butterfly Byway was completed in the Spring of 2018, and includes interpretive panels at prominent locations.
