Rain may be good for plants but not for pricey music equipment, mechanical rides and food trucks stuck in the mud.

The 100 percent chance of rain in the forecast Saturday means that the Wilmington Flower Market will be closed on its prime day for the first time in recent memory, according to Nancy Buker, the market's general chair.

That's bad news for the roughly 70 Delaware children's charities benefiting from the annual event at Rockford Park. In previous years, the three-day market has raised more than $200,000, including $150,000 on Saturday alone.

"When you close on a Saturday it's a big hit," acknowledged Buker, who made the decision with other organizers Friday evening. "We don't want to lose any more money than we have to."

The market, along with its first-ever beer and wine garden tent, will remain open until 8 p.m. Friday. For King & Country was expected to take the stage at 6 p.m. All plants are buy one, get one free.

Despite a soggy Thursday and country/pop singer LeAnn Rimes canceling her set at the last minute, the market attracted about 11,000 people during its first two days this year, Buker said. The 97-year-old event, always held on Mother's Day weekend, typically brings in 20,000 people over three days.
