The C&O Canal National Historical Park is beloved by millions for its natural beauty and rich recreational opportunities, but it is also one of the most biologically diverse national parks in the nation. The Park is home to over 100 rare, threatened, or endangered plants, some globally rare and unique. We’re featuring some of those plants on our Preserve Nature t-shirt to honor important conservation efforts in the Park. Let’s continue to protect these plants for future generations.

A portion of the sales supports the preservation of the C&O Canal through the C&O Canal Trust.
