IWGS Symposium 2026 | St. Louis, Missouri
AUGUST 18th – 21st

Where Water Gardeners Gather

Each year, the International Waterlily & Water Gardening Society brings together water gardeners from around the world. Growers, researchers and long-time hobbyists gather to learn, exchange ideas and spend time together.

In 2026, we meet in St. Louis, a city with deep botanical roots and a long-standing connection to plant research. Gathering here offers an opportunity to reflect on the work that has shaped water gardening while continuing the conversations that move it forward.
