Annual Meeting
Monday, July 22, 1 p.m.
Snyder Auditorium and Zoom
Speaker: Christine Hoffman, Twin Cities Flower Exchange
Christine Hoffman is a local flower advocate striving to form a strong community of sustainable flower farmers, small business owners, and folks who care about supporting these mindful endeavors. Her floral business, Foxglove, opened in 2013 and was the impetus for working with local farms and flowers. This led to the development of a local flower wholesale hub, Twin Cities Flower Exchange, founded by Christine in 2017. By providing local, sustainable options to traditional flower sourcing, she hopes to help foster change in the floral industry.
Topic: Local, sustainable, environmentally friendly flower growing and sales
Over 80% of the cut flowers we buy in the U.S. are grown overseas, but cut flowers are once again on the rise as a value-added specialty crop for small American farms. Twin Cities Flower Exchange was developed as a hub for selling cut flowers to wholesale buyers. As the first and only 100% local and chemical-free wholesale market in the country, The Exchange is creating a new model for the wholesale floral industry and fostering a vibrant local floral economy.
