The Asplenium ruta-muraria is a small plant known as the wall-rue fern. Even though it's called "rue," it's actually a type of fern and not closely related to the herb called rue. In Germany, people call it Mauerraute or Mauerstreifenfarn.
This tiny fern loves to grow on rocks, especially limestone and other rocks that contain calcium. Its leaves, called fronds, are a pretty bluish-green color. They are also very divided, meaning they have many small sections, and can grow up to 12 centimeters (about 5 inches) long.

About Wall-Rue Ferns
Wall-rue ferns are part of a large group of ferns called Asplenium. Scientists have studied these ferns to understand how they are all related. The wall-rue fern belongs to a group that often grows in rocky places, sometimes even sheltering among rocks in open areas.
One special thing about the wall-rue fern is that its leaves don't have hairs, which is different from some other ferns in its group. Scientists are still learning about wall-rue ferns, and they think there might be a few different kinds of wall-rue ferns that look very similar.
Where Wall-Rue Ferns Live
The wall-rue fern can be found in many parts of the world. It grows naturally in Europe, East Asia, and eastern North America.
Wall-Rue in North America
In North America, you can find wall-rue ferns in places like the Appalachian Mountains, stretching from New England all the way down to Alabama and Tennessee. They also grow in the Ozarks region and in parts of Indiana and Ohio. Sometimes, you might even spot them in Michigan, Ontario, Quebec, and Clinton County, Iowa.
Wall-Rue in Europe
In Europe, wall-rue ferns are quite common. They often grow on old stone walls and buildings, which is how they got their name! In the United States, they are a bit harder to find. They prefer to grow in small cracks and pockets in very old, dry limestone rocks.
