Hippeastrum glaucescens

Hippeastrum glaucescens belongs to the family of the Amaryllidaceae and the genus Hippeastrum, which is primarily known through the breeding forms of the amaryllis. This genus comprises 116 species that are mainly native to tropical and subtropical regions of South America. Hippeastrum glaucescens is one of the lesser known species that are valued in botanical gardens and collections due to their special flowers and robust growth.

Taxonomy and distribution

The scientific name Hippeastrum glaucescens is made up of the gene name Hippeastrum, which means from the Greek "rider star", and the art epitheton glaucescens, which indicates the blue-green or greyish coloring of the plant. The species was first described by botanical researchers, which they discovered in the tropical regions of Brazil. It grows there in damp forests and on river banks, where it is well adapted to the high humidity and the fluctuating rainfall.

Morphology

Hippeastrum glaucescens is a persistent, herbaceous plant that grows from an onion. The onion is underground and stores nutrients that enable the plant to survive during the dry season. The leaves of this kind are shaped linearly to lanceolate, with a bluish green or glaucoma surface, which gave the plant its name. The leaves can be up to 60 cm long and about 5 cm wide.

The inflorescences of Hippeastrum glaucescens are particularly striking and characteristic of the genus. The inflorescence consists of a long, leafless stem that wears a sham dolding stand that contains several large, funnel -shaped flowers. The flowers usually have a green red color. On the edge they are red and the chalice appears in a green color. They have six petals that are symmetrically arranged and develop into an open, star -shaped shape. Each flower can reach a diameter of up to 15 cm and spreads a pleasant fragrance.

Another interesting feature of Hippeastrum glaucescens are the stamens, which consist of long, curved filaments and protrude far from bloom. The dust bags are colored yellowish and produce fine pollen that ensures pollination by insects.

Ecology and reproduction

The flowers of Hippeastrum glaucescens specialize in insect pollination. Bees and butterflies in particular are attracted to the size, shape and fragrance of the flowers. The pollination is carried out by the transfer of pollen, which is stuck to the insect bodies, while they are nectar from the flowers. After successful pollination, fruit capsules develop from the flowers, which contain numerous black, winged seeds. These seeds are spread by the wind, which means that the plant can colonize new habitats.

In their natural habitat in Brazil, Hippeastrum glaucescens is adapted to the climatic conditions of tropical and subtropical forests. It thrives in partially shaded to sunny areas, preferring well -drained, nutrient -rich soils. The plant is relatively resistant to dryness because it is able to store water in its onion, which helps her to survive dry periods.

Cultivation and use

Like many other types of Hippeastrum glaucescens is occasionally cultivated as an ornamental plant. Because of its beautiful flowers and its ability to adapt to pot cultures, it is estimated. The onions can be planted in well-permeable potting soil and require regular irrigation, especially during the growth and heyday. After flowering, irrigation should be reduced to enable a rest period.

Compared to the more well-known Hippeastrum hybrids, which are sold as amaryllis, especially in the Christmas season, Hippeastrum glaucescens is less common on the market. However, it is valued in botanical collections and among lovers of exotic onion plants.

Threat and protection

In their natural environment Hippeastrum glaucescens has not yet been classified as endangered, but the loss of habitats due to deforestation and agricultural use in Brazil could have long -term effects on the populations of these and related species. The protection of tropical forests is therefore crucial for the preservation of biodiversity, including such less well -known plant species.
