Osmund (lat. Osmunda) this is a kind of fern of the moderate zone of the Osmundaceae family. The genus was named after the Ottomunder, the Saxon god of war, Osmunds elegant, medium and largeleaf fern with erect or arcuate branches, carrying their disputes on modified fruitful stems.
Description
The Osmund family is predicted in the form of a very large, dendroid fern. In places with sufficient humidity, it can grow in sunny places. Prefers acidic soils. Adults make disputes on separate branches.
Fern in the garden give an interesting texture and color shaded areas. Osmunda has large twice dissected leaves and gives elegance to the site if it is planted on shady flower beds with companion plants with contrasting foliage. Papornipot care is simple if you grow it in the right place.
Appearance
Pea-green branches are widely lanceolate and double. The outer branches are sterile, and the central branches have barren lower shields (leaflet or primary division of the cirrus of a complex sheet) and fertile upper shields. The fertile shields do not have pericularity, and their veins are covered with capsules with spores, which after ripening become brown and resemble the dead flowers of the genus Astilbe. The plant gradually builds up a lot of crowns and matte black roots at an altitude of 60-90 cm above the ground. By the way, roots are often used as an ingredient in compost for orchids called osmund fiber.
Kinds
Of the thousands of fern, only some are quite popular and acclimatized to the weather and natural conditions of our country. You can choose from this list the one that is right for you and your landscape needs.
Osmunda asiatica
This variety in general does not belong to this genus, and is allocated in a separate genus. However, the appearance and conditions of growth are identical to other types of pure.
Osmunda Regalis
At a young age, they have a reddish-violet color, and after full growth, the leaves become green. In the summer, the royal fern becomes brown. Another related look, Osmunda Spectabilis, has more slender forms, but outwardly very similar to the royal fern. Includes varieties:
Osmunda CleyToniana
The leaves of this species all the time are green until they fall off at the end of September. However, they are divided in the middle or rather interrupted by spikes. Needles grow in the center of the branch, giving the plant the shape of a vase. An adult plant grows to 2-3 feet, which makes it suitable for small rooms.

Osmunda Japonica
Osmunda Japonica grassy fern with erect, rising or briefly creeping rhizome. It forms the accumulation of branches, each of which reaches 150 cm in height and 50 cm in width.
Osmunda Japonica
Osmunda Rugii
One of the rarest fern found in this part of the world. This is a hybrid that occurs naturally when the types of Claytoniana and Regalis grow in close proximity. This hybrid is sterile, and only a few copies are recorded. Some experts attribute it to the period 1100 years ago.
Osmunda cinnamomeum
One of the most popular and colorful ferns. In the spring, the plant begins to turn green, but with the onset of summer, the leaves become orange, and in the fall brown. Leaflets are also characterized by small woolly hairs under them.

Where it grows
Originally from Europe, Africa and Asia, the royal fern is believed to develop on the southern continent of Gondwan. In fact, he is considered a living fossil, which has not changed much over the past 180 million years. The fossil remains of this plant impressive in their architecture were discovered in 2014 in volcanic deposits in the south of Sweden in the Korsared region, northeast of the coastal city of Malmo.
If you decide to grow this fern at home, consider that Osmund loves constantly moist soil, acidic and rich in organic substances. However, its varieties adapt to less favorable conditions, provided that. When planting a purely extent, leave free space around the plant so that it reaches the optimal height and scope of 60-90 cm. Also, when growing a royal fern, keep in mind that welllocated copies can reach 2 meters.
Choosing where to plant a purely, first inspect the place to make sure that the soil remains wet and the shadow is available most of the day. If sunlight enters the site, it should be from the morning sun or a limited late evening sun. Before planting fern in the garden, a soil analysis may be required to determine acidity. Adding compost, crushed oak leaves or pine needles will improve soil drainage and increase its acidity. If necessary, prepare the soil a few weeks or months before planting the uterine fern in the garden.
Reproduction
Purely must not be grown from seeds, since it produces disputes that sprout in the prick. Pritalia is a small, heartshaped prophet, which should undergo the process of fertilization before the roots and leaves develop. The process of germination of spans can be quite complicated for a novice gardener, since it requires sterilization, using the corresponding base for germination and constant temperature.
After maturation and drying, sterilized disputes should be poured into a fibrous sowing environment mixed with vermiculite, and stored in a moistened glass or plastic container. The container must provide access and air output, but should mainly help retain moisture. It should be kept in a greenhouse or a refrigerator, where a temperature of about 20 ° C is maintained, for 2-6 weeks or until a successful germination.
As soon as the thawed, they must be transferred to a small, slightly sifted soil mixture to another container. Developed young branches indicate that the plant should be transplanted into a pot with a rude, rich in organic soil. Throughout the process, a juvenile fern should not be exposed to direct sunlight.
If you do not have the opportunity to create suitable conditions for germination of the dispute, the ideal option would be the propagation of the plant with division. First dig the entire root system of the plant so that you can separate the root lump. The right time for this is in the spring, when the plant will need to be transplanted. Use a sterilized knife to gently divide the root lump in half. If the plant is large enough, you can divide it into quarters, making sure that each of them has its own set of leaves. Plant each division under moisture soil with a layer of at least 5 cm. Ensure constant moisture until the Delenki are rooted.
Red Book
The plant belongs to the category “in critical condition”. The reduction of the population is due to the drainage of the swamps and the cutting of forests. At the moment, about 9 locations of this type are known.
