April is Native Plant Month

Springtime on the C&O Canal brings new blooms just in time for National Native Plant Month in April! Celebrate at home by planting native wildflowers, removing invasive species in your garden, and spread the word about the importance of native plants in our local ecosystems.

Did you know that the C&O Canal is one of the most biologically diverse parks, with one of the highest concentrations of rare, threatened and endangered (RTE) plant species in the eastern United States? Help us preserve and protect the larger natural ecosystem of the C&O Canal. Get involved this April by giving a gift to the C&O Canal Trust or joining us this year for our public volunteer Canal Community Days events.

Why are native plants so important? Why should we care?

Native plants provide habitat and food for wildlife. They are the primary source of food and shelter for a wide range of wildlife species, including birds, insects, mammals, and reptiles. These plants provide essential nutrients and shelter for animals, including food for larvae and insects that pollinate flowers, fruits, and vegetables.
Native plants support biodiversity. They provide food and shelter for insects, which, in turn, support other animals and plant species. Native plants also help to prevent soil erosion and maintain the balance of the ecosystem.
Native plants are adapted to local conditions. They are acclimated to the local climate and soil, which makes them more resilient and better able to withstand drought, floods, and other environmental stresses. This means they require less maintenance and water, making them an excellent choice for homeowners and gardeners.
Native plants improve soil health. They have deep root systems that help to improve soil health by increasing soil organic matter and reducing erosion. This means that they can help to prevent nutrient runoff and protect water quality
Native plants have cultural significance. They have been used for centuries by indigenous communities for medicinal, food, and spiritual purposes. By preserving native plant species, we can help to protect and celebrate cultural heritage.

Below are some of the native spring wildflowers found within the C&O Canal. While you are out in the park, see if you can spot them! We encourage you to submit pictures of plants you find in the park to our monthly photo contest.
