Rotary Botanical Gardens celebrates Founders Day by honoring the birthday of Dr. Robert Yahr and everyone who helped turn an abandoned sand and gravel quarry into the botanical treasure it is today. What began as Dr. Yahr's dream, backed by the willingness of two Janesville Rotary Clubs, has grown into a garden with over 4,000 plant varieties, a collection of themed gardens, and a community that keeps showing up to support it. Founders Day is a chance to celebrate that legacy and the volunteers, horticulturists, donors, and staff who keep RBG growing today. Guests are invited to pay what they can to support RBG's mission. The day is a celebration for the whole community, honoring the people and generosity that built the gardens and continue to sustain them.
