The Pentagramma triangularis is a cool plant known as the goldback fern. It gets its name because the underside of its leaves often looks like it's dusted with gold! This fern is native to Western North America. You can find it growing in places like California.
This special fern loves to live in certain types of forests. It grows well in mixed evergreen and oak forests. Sometimes, you might even spot it on dry, brushy slopes. The goldback fern really likes shady spots. It prefers areas where the sun doesn't shine too brightly all day.

Meet the Goldback Fern!
The goldback fern is a type of fern. Ferns are ancient plants that don't make flowers or seeds. Instead, they reproduce using tiny spores. The Pentagramma triangularis is a unique fern. It stands out because of the yellowish powder on the back of its fronds. This powder can look like gold dust. It helps protect the fern from drying out.
What Does It Look Like?
The goldback fern usually grows to be about 4 to 16 inches tall. Its leaves, called fronds, are shaped like triangles. They are green on top. But if you flip them over, you'll see the amazing golden or yellowish powder. This powder is made of tiny glands. These glands produce a waxy substance. This wax helps the fern survive in dry conditions. It also protects the spores.
Where Does It Live?
This fern is found across a wide area. It grows in Western North America. This includes many parts of the United States and Mexico. In the U.S., it's common in California. It also lives in the Northwestern United States and Southwestern United States. You can find it in places like British Columbia in Canada. It also grows in New Mexico.
The goldback fern likes specific habitats. It often grows in forests with a mix of evergreen and oak trees. It can also be found on rocky slopes. These areas usually have some shade. The fern prefers soil that drains well. This means the water doesn't sit around its roots.
How Does It Grow?
Like all ferns, the goldback fern reproduces using spores. Spores are like tiny dust-like particles. They are found in special cases called sporangia. These sporangia are often grouped together. They are usually on the underside of the fronds. For the goldback fern, these are hidden by the golden powder.
When the spores are ready, they are released into the air. If a spore lands in a good spot, it can grow into a small plant. This tiny plant is called a gametophyte. The gametophyte then produces new fern plants. This life cycle is different from plants that make seeds. It's a very old way for plants to reproduce.
Different Kinds of Goldback Ferns
Sometimes, plants of the same species can have small differences. These are called subspecies. The goldback fern has a few known subspecies. One is P. triangularis subsp. semipallida. This one is sometimes called the pale goldback fern. Another is P. triangularis subsp. triangularis. This is the most common type.
Scientists sometimes change how they classify plants. Some ferns that used to be considered subspecies of Pentagramma triangularis are now seen as their own separate species. This happens as scientists learn more about plants. They use new information to group them more accurately.
