Selaginella

Selaginella

Selaginella is a multifaceted and one-of-a-kind spore relic plant that has survived in the subtropical and tropical regions of the planet and is successfully grown as a pot culture or in florariums at home. Caring for it cannot be called simple, Selaginella requires high humidity conditions that are difficult to create at home.

But inexperienced and caring hands, this thermophilic exotic turns into luxurious miniature rugs, ampels and pillows with a delightfully noble dense coral-laced texture. The Jericho rose or plunok, as this fossil flower is also called, has an impeccable reputation among florists when creating exquisite interior solutions.

General description

Selaginella is the only representative of the Selaginella family of the same name. It is an evergreen spore plant, which is why it is often ranked among ferns. Due to the large number of varieties, it is possible to describe the appearance of the flower only approximately – it has small fronds, in shape having a distant resemblance to corals due to its tiled structure. It is associated with coniferous or fern ground covers, some varieties resemble tall moss. The color of the leaves can vary in a wide palette of shades from light green and almost blue to rich dark tones.

Their size does not exceed 0.5 cm, the arrangement is usually two or four rows. The color is also ambiguous – uniform, with gradient transitions or with a fine structure of a variegated pattern. Shoots can be lodging, ampelous, and also short, erect, ascending or able to climb low obstacles. Throughout the calendar year, the external appearance of the plant practically does not change, there is no period of pronounced dormancy.

Despite the name “Ierekhonskaya rose”, the stem, like all spore crops, never blooms.

Species diversity

There are varieties of Selaginella, according to various sources, from three to seven hundred. Among them there are also those that live on trees and are epiphytes. About 25 species are suitable for growing at home; they may differ in care due to their different adaptability to environmental conditions in places of natural growth. Most selaginella suitable for home breeding can be found in private collections very rarely. Typically, in indoor floriculture, the following seven planters are found in descending order of their popularity and the ability to purchase seedlings.

Outwardly, a spectacular medium-sized ground cover, reaching 30 cm in height. The dense lace crown is formed of frond with tiny bright green leaves, folding into a textured pattern. Shoots are straight, but strongly elongated, prone to lodging. Over time, aerial roots begin to form on them. Within this variety, the watsoniana form stands out, featuring silvery-white stem tips that are often mistaken for flowers.

It is distinguished by longer shoots, which, due to their high flexibility, create exquisite ampelous shapes, and when grown on a relatively large area – unusual carpets. Their originality is given by the special root growths characteristic of this species.

A characteristic difference from other varieties is the bushy shape of the stems, which also have dense branching. Their surface is smooth, flat section, thin leaves. Bears great resemblance to miniature conifers. Excellent for growing in ampelous version. The bluish color of the leaves contrasts with the green color of the stems.

Groundcover, very compact, forming a low carpet that resembles moss. In this case, the castings themselves, and not the stems, spread along the ground cover. The sod is very thick and dense. It can also be grown as an ampel.

A very unusual and even strange plant that can be found on sale in the form of dry balls, which should be put into water to awaken to life. After that, absolutely dry, colorless and without signs of life, the lump magically comes to life, opens up and becomes bright green, acquires freshness and a very attractive appearance. But as soon as the humidity drops to critical levels again, the flower will again very quickly turn into a dry ball. Adult shoots grow up to 10 centimeters in length, and with a lack of moisture, they twist, forming a ball. It was this variety that received the name of the Jericho rose for this feature, which spread to the entire family. You can also hear the variant “resurrection plant”.

The ability to fold and resurrect is associated with the presence of a large amount of oils in the composition of cell sap, which do not allow the flower to dry out completely. However, there is also a limit to this endurance. Specimens that have been found without access to moisture for too long dry up forever, and it is no longer possible to bring them back to life. By the way, on sale such “dead” are quite common, so it is better to check them for viability as soon as possible.

Unlike other members of the family, this one has a rather loose sod, formed from curly tiny leaves sitting on thin stalks. However, their arrangement is strictly organized, which makes the crown strikingly graphic. Other features are the perpendicular arrangement of leaves relative to the shoots and a lighter color than other members of the family.

Selaginella can be grown in terrariums, florarium compositions and other closed and semi-closed volumes, including bottle versions. They create warm-humid greenhouse conditions, under which the spade feels very comfortable.

Home care

Almost all selaginella representatives grown at home are warm and moisture-loving, but it is better to clarify the exact characteristics of a particular variety with the seller.

Lighting

Plaunok is a resident of humid, semi-shady places, so a place for it should be allocated to places with moderate illumination, where direct sunlight does not reach. If it is a window sill, then only a north or northeast orientation, where light-loving plants do not survive well. However, even in the depths of the room, where there is very little light, you should not put the plummer, this will reduce its decorative effect, make it looser and more spreadable.

Temperature content

The temperature requirements of the culture are average, within + 18 … + 22C, in winter the air in the room can be cooler. The lower permissible limit is + 12C, this is a critical temperature for a flower, and only the Krauss and Bezlegkovy species can transfer it. Others require warmer conditions, and some require exceptionally higher + 20C at any time of the year.

Selaginella tolerates drafts extremely negatively; it should not stand in the way of any movement of air masses.

Watering, humidity

Watering, with all the love of the exotic for moisture, should be moderate, without stagnant water, since its root system is easy to rot. As for the humidity of the air, it should be as high as possible; at every opportunity, you can pick up a spray bottle and irrigate the crown. The jets should be finely dispersed, and the water itself should be filtered or well-separated, soft, without lime content. After spraying, no drops should remain on the branches. You can go according to the principle of lower moistening and place the pot near a container of water or on stones in it in order to avoid excessive saturation of the earthen coma with moisture.

Topdressing

Twice a month, during the period from March to mid-autumn, it is recommended to make top dressing intended for decorative deciduous crops. The rate should be taken half of that recommended by the manufacturer.

Substrate

The ideal composition of the soil for the pond is an equally weighted mixture of turf soil, compost, sand and light high-moor peat. In general, the soil should be loose and nutritious, with a high level of moisture permeability. Bottom drainage will help improve it. It is better to choose a plate wide, flat, its height is calculated for a high-quality drainage layer and a superficial root system. It is very good to add chopped sphagnum to the soil mixture. The acidity index should be low, no more than 5-6 units.

The stems of the root part tend to bare over time. In order to preserve decorative qualities, plants should be updated in a timely manner.

Transfer

The approximate frequency of transplanting is 2 years, in the first years you can do it earlier, old plants are less disturbed. New dishes are chosen wider, the height of the pot may vary slightly, the roots of the Jericho rose are shallow, and grow in breadth.

Reproduction of selaginella at home

In the presence of at least one plant, the easiest way to propagate the culture is with the help of cuttings. Usually, they remain in excess after crown molding, if the task is to create a certain compositional solution. The flower tolerates pruning well, cuttings can be cut on purpose at any time, but traditionally a more suitable period for this is spring or early summer. You can also easily divide the bush along with the roots during transplantation, this will serve to rejuvenate the specimen and provide the necessary planting material.

For rooting, you can use a peat-sand mixture or any other light loose substrate with low acidity. Cuttings root easily in water.

Pests, diseases, growing problems

The crop’s resistance to infections and insect pests can be called high. But with excessively dry air and a lack of watering, the flower can be affected by spider mites, especially if the infection has touched neighboring plants.

Of the most common growing problems, the following can be distinguished:

  • Browning of the tips of the shoots and their gradual drying out is a sure sign that the regime of high humidity is not being observed. The situation is aggravated by insufficient watering and maintenance in conditions of high temperatures.
  • If the shoots dry, shed their leaves, or turn brown not from the tips of the shoots, but along the entire length or in places, this may indicate a burn from direct sunlight.
  • Lethargy, loss of turgor of leaves and shoots, their softness to the touch are the result of waterlogging of the soil or its increased density, too low coefficient of air and moisture permeability.
  • Elongated shoots with sparse internodes are evidence of insufficient lighting.

Selaginella - growing at home

Selaginella is an excellent candidate for tropical exotic plants for creating a home exposition of rare and relict crops with a general landscape design and a high humidity microclimate.
