The right to wear the generic name Asplenium has a huge number of ferns that live in different parts of the world. All aspleniums are perennial herbaceous plants that have adapted to live not only on a loose substratum, but also on trees and even stones.
Under such different conditions of existence, the ferns are strikingly different in size and appearance. Among the Aspieliums there are like real giants with a rosette of meter-long leaves, and tiny ten centimeters copies hiding from the cold wind between the stones.
Aspenium of the nesting (A. Nidus)
Asplenium or, as the second name of the plant sounds, the stake is represented in all parts of the world. The leading way of life of the epiphyte is the bone or asplenium nesting, in nature you can see in the humid tropics. Traveling through the thick deciduous forests of Polynesia or southeast Asia, on the trunks of trees you can see large rosettes of whole elongated leaves. This is the Nidus asplenium.
In a warm climate the fern reaches considerable dimensions, and the length of one leaf can exceed 100-120 centimeters. Unlike many other species of fern, in this case the leaves are solid, leathery or oil-like to the touch. The color of the leaf plates is light green.
Since the plant in nature is an epiphyte, its rosette is arranged so that the nutrients and moisture that enter the center quickly reach the thick fern rhizome.
The photo of this species of asplenium shows that the sporangia are located on the back of the leaves and represent convex brownish-brown bands. The central vein of the leaf is dark, on the reverse side it is round-convex.
The appearance of the fern determined its popular name “nest”. Indeed, the funnel-shaped rosette is very dense and when attached to the stem it is very similar to the nest of a huge bird.
Despite the fact that the aspen (nesting) nest is from the tropics, the fern feels well in the apartment, although the existing varieties are somewhat more compact than the natural form and can easily find a place on the windowsill.
In nature, there are two varieties of this interesting plant. In the photo there is an asplenium nidus Plicatum with corrugated foliage. Discovered half a century ago, a wild specimen became the basis for selection work and obtaining several popular varieties today.
Another variety of asplenium nidus Fimbriatum is an amazingly attractive plant with foliage chaotically dissected around the edge. And this kind of asplenium, as in the photo, also found application in indoor floriculture.
Asplenium viviparous (A. viviparum)
The homeland of this unique species of fern is Madagascar and other islands of the Pacific region. For lovers of indoor plants, viviparous viviparum (A. viviparum) interest is not only pinnate bright green foliage, which forms a decorative openwork rosette, but also a method of plant multiplication.
In the tiny sporangia, spores form on the ends of the threadlike parts of the leaf, from which directly on the mother plant the daughter rosettes develop. Gradually forming plants sink and take root in a light loose ground.
Asplenium viviparous is very similar to another species, using the same method of reproduction. This is an asplenium bulbous, whose description and photos are given below.
Asplenium bulbous (A. bulbiferum)
Wild specimens of bulbous-asian plenum can be seen in the tropical forests of India, New Zealand and Australia. If we compare this species of asplenium and the viviparous viviparous, then the segments of the leaves are noticeably larger, and the plant itself reaches a height of about one meter.
The petioles are hard, dark at the base and green on the top of the leaf. According to the photo and description of the asplenium of the bulbous, cirrus, the plant has pinnate, strongly dissected leaves with round-toothed segments of different shapes.
Presented in the photo of asplenium brood kidneys are located along the edge of the leaf and give life to young ferns, creating a miniature rosette directly on the mother plant. This feature of the fern makes it possible for the floriculturist to easily obtain a new generation of pets. To do this, only need to help the rosette take root in the nutrient substrate.
It is interesting that in the native land of the plant, in New Zealand, this kind of asplenium is called pikopiko or mauku, which means the laying hen, and the young leaves are used for food as a green culture.
Both in nature and at home, plants feel better in the penumbra, since the sun has a harmful effect on the feather foliage and young plants of the asplenium.
Aspenium scolopendrum (A. scolopendrium)
It is difficult to imagine, but the scopelindry aspleen shown in the photo is the inhabitant of European forest tracts. From Germany to Britain you can see wild specimens of this fern with whole leathery leaves up to 40 cm long.
In contrast to the nest-shaped asplenium, the skolopendrovy stone forms not such a powerful and dense rosette. In this case, the dark petioles are somewhat longer, and almost erect young leaves begin to flex as they grow.
If the root of the plant has slightly wavy edges, then subspecies crispum and undulatum can be observed foliage with beautiful corrugated edges. Such plants are highly valued by florists. Breeders have already presented fans of ornamental and deciduous crops several varieties and hybrids of spectacular, as in the photo, scopopendrovic asplenium.
Asplenium South Asian (A. Australasicum)
When looking at the photo of the asplenium of the South Asian plant, it can be confused with other species that have integral long leaves.
Fern native to the east coast of Australia and from Polynesia can live on the ground, under the crowns of the tropical forest, and the trunks of plants. At the same time, the species of asplenium pictured on the photo is a very large plant with 1.5-meter back-lanceolate leaves. The socket has the form of a dense, high outlet in the shape of a funnel or bowl.
Maturation of the spores passes on the inside of the leaf plate. Saurus linear, convex, located on the top of the leaf in a dark central veinlet.
Asplenium hairy (A. Trichomanes)
In height not exceeding 20 centimeters, elegant asplenium hairy does not form a pronounced rosette. Fern leaves lodging, elongated pinnate. On long brown-purple petioles are, as in the photo of asplenium, oval light segments.
In the wild, the plant prefers to settle on rocky protrusions with scant clumps of soil. The fern’s habitat covers some North African regions, Eurasia and the north of the American continent. The plant is winter-hardy and can be grown not only as a room, but also as a decorative garden crop.
Asplenium drooping (Asplenium flaccidum)
In the forests of New Zealand not only powerful representatives of the genus Asplenium grow, but also very unusual openwork ferns. Among them is the image depicted in the photo, the asplenium drooping – the epiphyte with many-sliced long leaves up to a meter long.
Asplenium ebony (Asplenium platyneuron)
A small elegant fern lives in the forest zone of North America. Asplenium, as in the photo, feels well both in the penumbra and in the shady places. With good endurance, common to all related species, asplenium ebony negatively refers to excess moisture. The height of an adult specimen can vary from 30 to 50 cm.
Petioles thin brownish-red hue. Leaf plates are light green, leathery. Depending on the location on the sheet, the segments have a size of 15 to 2 mm. The shape of the alternately arranged lobes is triangular or trapezoidal.
The rhizome is very short, requiring a small volume of soil, so asplenium, as in the photo, can be used for vertical gardening.
