Maine Greenhouse and Nursery Day was held Saturday at greenhouses and garden centers across the state, The Portland Press Herald reported.
Mary Lou Hoskins of Greencare Interior Landscapes in Hermon (just south of Bangor) came up with the idea, and it spread quickly.
"I made the mistake of opening my mouth," Hoskins quipped, "and they said fine, go ahead and do it."
The majority of the 30 participating garden centers were in central Maine. Hoskins said that is probably because she is active in the Mid-Maine Greenhouse Growers Association, and its members got behind the project.
Southern Maine participants include Risbara's Greenhouse in Portland; Plainview Farm in North Yarmouth; Estabrook's in Yarmouth, Scarborough and Kennebunk; Steeplebrush Farm Herbs in Limington; JoAnn's Flowers in Parsonsfield and Moose Crossing Garden Center in Waldoboro.
Hoskins thinks more nurseries and garden centers will get involved in the future.
"We all love growing plants. It's not just to make money," she said. "It's a passion. But we don't mind making money, too."
