6th Annual Winter Silhouette Show Highlights Bonsai Branch Architecture at Morton Arboretum

The Prairie State Bonsai Society returned to The Morton Arboretum’s Sycamore Room for its 6th annual Winter Silhouette Show on February 21–22, 2026, presenting leafless deciduous bonsai and select conifers from 10:00 a.m. to 4:00 p.m. each day. Entrance to the Bonsai Silhouette Show was included with Arboretum general admission, and the indoor setting in the Visitor Center allowed visitors to study branch lines and ramification up close.

Prairie State promotional text framed the exhibit succinctly: "This unique exhibit highlights the intricate architecture of deciduous trees in their dormant state, alongside select conifers." The Arboretum’s event description echoed that focus, inviting attendees to "view bonsai trees without leaves to appreciate their intricate branches." Exhibitors showed mature maples, elms, and other deciduous specimens whose winter silhouettes exposed wiring, branch collars, and wired apexes that are often concealed by a summer canopy.

A special "Trees in Training" collection ran alongside the main display to make technique visible. Morton Arboretum copy noted, "A special collection of trees in training will demonstrate how bonsai trees are developed and trained using wiring and pruning techniques that have been perfected over the centuries." The club emphasized that these developmental specimens were instructional; Prairiestatebonsai reminded members that "Trees are not expected to be ‘perfect.’" Ceramic pots and stands were used for most trees in the main show, while Trees in Training did not require formal stands, and the club maintained additional stands available for loan.

Vendors at the show supplied shopping options for participants and visitors. Morton Arboretum listings named BC Bonsai as selling "all things bonsai-related, including trees, pots, wire, and tools," and Bubba’s Backyard Bonsai as selling bonsai trees; the venue also advertised pots, accessories, and succulents among the retail offerings. Prairie State promotional material added a lighter draw: "Bonus: Don't miss the Juniper Junction model train display while you’re there!"

The Winter Silhouette Show continued a long-running relationship between the club and the Arboretum. Morton Arboretum materials trace the group's roots to incorporation in 1987 as The Morton Arboretum Bonsai Society and note the club became independent in 1994; the organization "has continued to work with the Arboretum for the past 35 years." The silhoutte exhibit moved to the Arboretum after prior Winter Silhouette Shows were staged at Cantigny Park in Wheaton, IL, where Cantigny’s Visitor Center redesign repurposed the space the club had previously used.

Community discussion around the event appeared in bonsai forums, where a thread titled "Prairie State Bonsai Society's 6th Annual Winter Silhouette Show - Morton Arboretum, Lisle, IL - February 21st-22nd, 2026" was started by package56, whose forum profile lists Arlington Heights, IL and USDA Zone 6a. The show's pairing of mature specimens with Trees in Training reinforced the educational through-line the club has emphasized for decades, and the Sycamore Room setting kept the focus squarely on branch architecture and the craft of wiring and pruning.
