Great MonArch Migration Event
The City of St. Louis and National Park Service partner annually to hold a community event on National Public Lands Day to celebrate the migration of the monarch butterfly.
The Great MonArch Migration Event 2021
The City of St. Louis and National Park Service have been holding The Great MonArch Migration Event the last Saturday in September since 2017 to coincide with National Public Lands Day. The Great MonArch Migration Event is held on the ArchGrounds at Gateway Arch National Park. Due to the need to observe physical distancing, the 2021 Great MonArch Migration Event will have a scaled-back physical presence.

Thanks to Grow Native!, Missouri Prairie Foundation, the National Park Service and Papillon Perennials, you will have the opportunity to safely pre-order/pre-pay for a pollinator-friendly collection of native plants, and collect them with physical distancing.

Plants - Each MonArch Garden In A Box costs $30 and you will receive nine native plants to create the ideal habitat for attracting monarch butterflies and other pollinators. The collection will include several milkweed and nectar sources, and align with the plant recommendations of the STL Monarch Mix (there may be some variation in species due to availability).
Pick Up - Between 10am and noon on Saturday, September 25th, there will be a dedicated spot at the Archgrounds near the Old Courthouse on Fourth Street for you to pick up your purchased plants.
Free Tote - The first 50 people to pick up their MonArch Garden In A Box at the Arch on September 25th will receive a Free Monarch Tote Bag, courtesy of Brightside St. Louis.
Come celebrate the spectacular monarch migration; bring your camera or phone to capture monarch butterflies on their migration route near the Arch. After enjoying the Archgrounds, collect your plants to create a monarch habitat in honor of National Public Lands Day.
There will be a table with some educational materials on site, but due to the need for social distancing, most of The Great MonArch Migration Event will be held virtually this year.
