Slow Flowers

with Diane Walden
Wednesday, July 11
1 – 5 p.m.
Thanks to the extraordinary strides made in the national food and culinary scene in placing emphasis on local sourcing and organic choices, there has been a sea change in the way we eat—this is the “Slow Food” movement. Apply that same thinking to sourcing your flowers, and you arrive at the “Slow Flowers” movement: Where do our flowers come from? How are they grown?
Any gardener has an up-close-and-personal relationship with flowers. They are a source of wonder and constant change as bud turns to bloom turns to fruit or seed or drupe. This diverse class—part-lecture, part demonstration, and part hands-on work—will provide you with an opportunity to share some of Diane Walden’s floral harvest from the Gardens, to learn about the evolving “Slow Flower” movement, the state of the global flower market, our own Maine-grown local markets, and to create your own arrangement.
