Sonnenberg Gardens

What Sonnenberg Gardens does

Sonnenberg Gardens & Mansion State Historic Park is a nonprofit historic estate and visitor attraction located in Canandaigua, New York, in the Finger Lakes region. The property encompasses approximately 40+ acres developed between 1902 and 1920 by philanthropist Mary Clark Thompson, featuring nine formal gardens (including the first residential Japanese Garden in America, created in 1906), a 40-room Queen Anne Victorian mansion designed by Boston architect Francis Allen in 1886-1887, and a 13,000 square foot Lord & Burnham Greenhouse complex built between 1903-1915. The estate operates as a New York State Historic Park under the administration of NYS Parks, Recreation & Historic Preservation, with a nonprofit Friends organization managing restoration, programming, and fundraising.

The organization generates revenue through a diversified set of streams: general admission (seasonal operation May-October, Thursday-Monday), ticketed special events (Arts at the Gardens, Moonlight Strolls, Haunted Stroll, Mansion Mysteries, Fall Gardening Forum, Father's Day Car Show, Afternoon Tea), memberships (personal, business, garden club), private event rentals (weddings, corporate events), group and bus tours, a Finger Lakes Wine Center featuring six private-label wines produced by four regional wineries, a gift shop (Bay House Gift Shop), and an independently operated cafe (Gardener's Cafe). Additional revenue comes from donations supporting ongoing restoration of the historic greenhouse complex. The customer base is primarily general public visitors, group tour operators, wedding parties, wine enthusiasts, horticulture enthusiasts, and members/supporters, with distribution channels including on-site admissions, online ticketing through the website, group tour direct sales, and joint combo passes with Granger Homestead and Carriage Museum.

The underlying technology is minimal in the digital sense. The core technology platform is the historic physical estate itself, which has operated continuously for over 100 years with original greenhouse frames and climate control parts still functional. Digitally, the organization uses a WordPress-based website with The Events Calendar plugin for online ticketing, a dial-in cell phone audio tour system with 19 stops, and organic social media presence on Facebook and Instagram. Marketing is event-driven and multi-channel, leveraging partnerships with regional tourism organizations (Visit Finger Lakes, Canandaigua Lake Wine Trail, ROC/FLX Craft Beverage Trail, American Horticulture Society reciprocal admissions).
