Ferns

Royal Fern
Royal fern, otherwise known by its scientific name, Osmunda regalia, is a type of fern that loses its leaves during the winter months. It grows naturally in boggy areas in some parts of Europe, Asia, and Africa. It can grow up to 63 inches tall and up to 16 inches wide. The royal fern produces both sterile and fertile fronds, with the fertile ones being a little shorter when the plant is fully grown.
There are many uses for the plant. The roods are commonly used to help orchids grow while the sporangia were once thought to contain magical powers to defeat demons and understand how the trees communicate. There is a lot of mythology surrounding how these sporangia are collected to thwart off the attacks of these so-called demons. The leaves are used in Korean cooking, and the shoots are eaten and taste similar to asparagus.

Shield Fern
The shield fern, also known as wood fern or buckler fern, depending on what part of the in where it is found. Its scientific name is Dryopteris and is most commonly found in the temperate regions of North America, such as the wet, wooded, shady forests of the Pacific Northwest, parts of Europe, and Northern Asia.
The average shield fern grows up to 3 feet tall and 2 feet wide. It loves wet soils but can live in dryer soils as well. If you are planting them in your garden, they will continue to look the best if you removed the damaged leaves once a year.
This genus is commonly hybridized and formed into many different species, and most of them have short roots that slowly creep into a crown shape. They are also the most common type that is used as garden greenery. Butterflies often lay their eggs in the leaves to that it can eat and grow.

Silvery Glade Fern
The silvery glade fern is also referred to as the silver spleenwort and has the scientific name of Deparia acrostichoides. This perennial fern is very stout and sturdy with deciduous compound leaves that are up to 3' tall and 1' across. The silvery glade fern gets its name from the fine silvery hairs that cover the center stalk, or the rachis, of the leaf blade. Also, there are sori (spore-bearing structures) on the leaves that are covered by the indusia, or protective membrane, that also give this fern a silvery appearance. In summer or early fall, the sori release the spores. This fern prefers light to medium shade and a moist to moderately moist soil environment. High humidity and protection from wind are also ideal growing conditions for this plant. The silvery glade fern can be found in woodland valleys, wooded areas, and also above streams in woodland ravines.
