LIMA — One of the area's most popular businesses is also one of its most popular spots to throw a party.For the past four years, the greenhouse and DeHaven's Home and Garden Showplace has been home to the annual Jazz at the Greenhouse event. The fundraiser for ArtsSpace/Lima draws hundreds of guests to the space each December to eat, drink and soak up the atmosphere. Owners Tim and JoAnn DeHaven not only offer up the space, but help plan and decorate and serve as unofficial host and hostess of the evening.“The DeHavens are the definition of hospitality. We could not do this event without the cooperation of the entire DeHaven family,” said Kay VanMeter, associate manager of ArtSpace/Lima.This year's Jazz at the Greenhouse will kick off at 8 p.m. Dec. 2. The Detroit jazz band Motor City Beat will perform. Tickets are $20 each or $200 for a table of eight. The Greenhouse is located at 775 Shawnee Road.The ArtSpace event is not the only thing the DeHavens have hosted in their greenhouse. JoAnn DeHaven, a two-time cancer survivor, has hosted annual “You're in the Pink” ladies nights as a fundraiser for the Northwestern Ohio chapter of the Susan G. Komen Foundation. Earlier this year, they hosted people coming in with their children or pets to have pictures taken with the Easter Bunny. The event was a fundraiser for the Humane Society of Allen County.“This is our way of supporting those things that make Lima Lima. That's important to us,” JoAnn DeHaven said.For all their fame as host and hostess, the DeHavens will not be able to attend this year's jazz show. The couple are spending their time in Columbus where Tim DeHaven is recovering from postsurgical problems that resulted in the amputation of part of a leg. He may not be back to the store in time for the show, but the famously driven businessman will undoubtedly be back.“He's doing much better. It's going to take some time, but he has every intention of getting back to the store and to life,” JoAnn DeHaven said.
