Cantigny welcomes back the Prairie State Bonsai Society for its 4th annual Winter Silhouette Exhibit. This event features bonsai trees without leaves — the best time to see their structure, especially the ramification. The latter refers to the practice of dividing stems or limbs into smaller branches, the goal being to create a dense, inward growth, resulting in a thicker canopy.

The one-day exhibit includes items for sale -- bonsai, pots, tools and other materials. Exhibitors are happy to answer questions and discuss their passion for bonsai! Admission is free with paid parking. Visit www.prairiestatebonsai.com for more information.
