Pseudananas Are A Great Alternative To Indoor Pineapples

, Admin

In recent years, among the bromeliads, it is not the most spectacular but the most undemanding plants that have become increasingly popular. Pseudananas is one of the not common, but more hardy and undemanding species. Despite its spectacular flowering, it used to be considered just a "poor relative" of real indoor pineapples. And only the tendency to find for modern interiors expressive and suitable for even the most inexperienced owners plants attracted attention to quite other merits of this plant.

Pseudananas is not exactly an unsightly relative of ornamental pineapples

Pseudananas is considered a relatively young crop. It was discovered only at the end of the 19th century, and in its greenhouse form and in the botanical gardens of Europe it appeared only in the last century. The plant has long been regarded in the genus Pseudananas as one of the amazing Latin American endemics, represented by a single species, Pseudananas forage, or Sagenarius (Pseudananas sagenarius).

A recent revision of the classifications has resulted in the plant still being included in the genus Pineapple as a separate and distinctly distinct species from its relatives, Pseudananas sagenarius. In literature, western catalogs and retail sales, pseudananas are still sold under the old name of pseudananas and the debate about its status continues.

Despite the name directly indicating a similar appearance, pseudananas are mistakenly perceived as an alternative or copy of the common pineapple. This crop is capable of surprising both in its ornamental qualities and in its purely practical characteristics, it differs from its counterpart quite strongly.

In nature, pseudananas are found only in South America. It is most widely represented in Bolivia and Brazil, although it is also found in extensive Ecuadorian, Paraguayan and Argentine forests.

Ananas, or Pseudananas sagenarius, or fodder (Ananas sagenaria, synonym Pseudananas sagenarius) is a species that is often associated with large-crested pineapples, but the differences still seem striking when comparing the two plants.

Despite their kinship, only one trait is truly the same: large, cone-like inflorescences, which are transformed into easily recognizable copulas. The Sagenarius pineapple looks much more "wild", it has a less strict leaf pattern in the rosette, less compact size even in the best varieties, and the foliage looks sloppy. But its ability to tillering is better. In terms of development cycles, Pseudananas is a typical bromeliad. Its mother rosette dies off after flowering.

Pseudananas are large plants and require a lot of space. The main foliated "stem" grows to 1.5-2 m in length. At the base of the main shoot rosettes continually produce short, thickened stems that bear daughter rosettes, which completely replace the mother plant after fruiting is completed.

Young rosettes of pseudananas look neat and do resemble a crested pineapple. As adults, however, they become more and more "wild" in appearance. The plant together with the babies gives the impression of exotic thickets.

The leaves of pseudananas are impressive in both width and length. Unlike the leaves of the crested pineapple, the base of the leaves of this pineapple can be as large as 7 cm. The sprawling, sparse, often asymmetrical rosette contains up to 40 mead-like leaves of a bent-vaulted shape with a deeply grooved cut and an irregularly wavy surface.

With a length of over 1 m, the leaves of Pseudananas appear particularly prominent in adult rosette. The glossy surface of the leathery leaves is combined with light scales on the underside and hook-like brown spines along the edge.

Pseudanaceae blooms very spectacularly. The short, up to 30 cm long flower stalks with a glaucous scale effect on the surface are crowned with a large simple inflorescence-colossus with rusty, shortened bractal leaves, petiolate lanceolate bracts with serrated margin and bright pinkish-red coloration and sessile flowers up to 5 cm long with asymmetrical orange tepals and straight lanceolate petals with an unusual narrow purplish-colored bend and white marigold.

Flowers and sepals are equal in length, stamens are attached to petals, which only emphasizes the "purity" of the inflorescence lines. Cones of Pseudananaceae are up to 17 cm long and 9 cm wide, holding up to 200 flowers. Flowers open gradually, one by one, from bottom to top. In contrast to the greenery of the plant, the inflorescences appear symmetrical and surprisingly regular. The bright red inflorescences are superdecorative, on bushes they seem to be an exclusive decoration.

After the blossoming, the edible, juicy, very beautiful copulas of pseudanasses are set. They are often a few centimeters larger than the inflorescence (up to 20 cm long and 10 cm wide). The pseudo-berries take a very long time to mature, changing in color as they mature into a bright scarlet with a pink tint.

Conditions for growing indoor pseudananas

The Sagenarius ananas is the most unpretentious of all pineapples, adapting surprisingly well to living quarters and requiring no special conditions. A slight drop in temperature over the winter is the only measure needed for its good blooms. If pseudananas overwinter in warm temperatures, it still retains its ornamental greenery and ability to tiller, but may not flower annually (which is not always a disadvantage when grown in mixed compositions, it also happens when it is cold overwintered).

Pseudananas are ideal candidates for creating tropical gardens and wild exotic effects in greenhouses and conservatories. It is a large, massive plant that immediately sets the mood. It is recommended to be grown in rooms that rely on exotic crops or where you want to create a sense of thematic landscaping.

In single lots, this plant will not be lost either. It adapts to living rooms better than many other bromeliads and is appropriate wherever there is no need to choose emphasized neat and symmetrical, "correct" crops and bushes, is a wonderful wild-looking alternative to the strict lines and orderliness of modern stars.

Lighting and placement

Pseudananas prefer sunny locations or the brightest possible diffused light. Sills on south, west and southwest windowsills are ideal for them, but when choosing a place, you have to consider the difficulty of placing the plant because of its size.

The size of adult Pseudanaceae, although the optimal location remains on a window sill, rarely allows you to put the containers directly on it. Pseudananas are placed as close to windows as possible.

When purchasing pseudananas, the spreading and tillering of this bromeliad should be considered. Pseudananas need to be given adequate space. Large, sprawling rosettes, combined with smaller plants growing at the base, need some distance from other plants, and stiff spines make any contact with the leaves unpleasant.

Temperature and ventilation

Pseudananas are comfortable in room temperatures. During the period of active growth, any temperature in the range from 20 to 25 degrees will suit them. The heat harmfully influences on decorativeness of leaves, but nothing terrible will happen to the plant at higher air temperatures, if correct watering and humidity in time. The temperature should be lowered by at least 2-3 degrees - to 15-18 degrees of heat. This plant does not like cold weather, it winters well in warm and stable temperatures, but it can bloom more seldom or atypical times. © L'herbier en photos

Home Care for Pseudanassus

The Sagenarius ananas is an excellent unpretentious alternative to the common pineapple and a larger, sprawling plant. Its care is so close to the average standards of care for houseplants that this bromeliad can be recommended to inexperienced florists as well. Careful watering, infrequent feeding is all this plant needs.

Watering and humidity

Pseudananas remains a typical houseplant with substrate moisture requirements. In spring and summer it is watered so abundantly that the substrate always remains moist, between these procedures only the uppermost layer of soil in the containers is dried out. Pseudanasses use classic watering, not pouring water into the socket.

Water treatments should be as careful as possible, trying not to soak the base of the stems and leaves, pouring water around the perimeter of the containers. Humidity, excessive moisture the plant can not stand, with overflow the ground lump is dried more thoroughly. In autumn, watering is gradually reduced and the plant is transferred to minimal procedures with drying of the substrate between watering.

Pseudananas is not demanding to air humidity. It is only necessary to increase the humidity in hot weather or when heating systems are in operation. The plant is content with simple spraying, although humidifiers can be installed if growing in collections.

Fertilizers and fertilizer composition

Fertilizer excess is as dangerous for Pseudananas as soil depletion. The plant is fertilized in spring and summer once every 3 weeks, with standard doses of fertilizer. In the fall and winter, carry out weakly concentrated fertilization once every 5-6 weeks. This culture uses special fertilizers for bromeliads.

Transplanting and substrate

For Pseudananas choose large, wide containers, allowing the free development of lateral rosette. It is not necessary to increase the volume of the pots for the plant too much, but it should be given space to develop for several years. The width of the container should be greater than its height.

Pseudananas are transplanted only during the phase of active growth (from early spring to mid-summer), after the plant has fully mastered the container in which it is growing. There is no need to transplant every year if the pseudananassus has somewhere to grow.

Selecting substrate for pseudananas, it is better to stop at loose, light mixtures. The usual ready-made substrates for bromeliads are ideal. You can prepare the mix yourself, mixing leaf, sod soil, peat and sand in a ratio of 2:1:1:1 and making a handful of digging additives and inert materials.

When transplanting in pseudananas necessarily remove the old rosettes, if desired, separate bushes. Take care not to injure the small roots of the plants. The level of embedding is kept the same.

Diseases, pests and problems in growing Pseudananas

It is one of the most resistant indoor bromeliads. Pseudananas are threatened only by rot when the above-ground parts are overwatered or wet, and by spider mites in an extremely neglected state.

Save a plant affected by rot can only be saved by emergency transplanting with separation. But spider mites can be easily dealt with by correction of care, combined with spraying with insecticidal preparations. Also common in this plant is leaf tip drying as a result of keeping it in heat or in very dry air.

Pseudananas reproduction

The only method available for home propagation of pseudananas remains splitting - separating the lateral rosettes during transplanting and rooting them as independent plants. Rosettes with less than 4 leaves and without good independent roots in this crop are not separated.

Pseudananas are grown from seeds only under industrial conditions, and very rarely.
