Care of the plant Alpinia purpurata or Red ginger

The genus Alpinia, family Zingiberaceae, includes about 230 species of tropical plants native to Asia, Australia and the Pacific islands. Some species are: Alpinia purpurata, Alpinia zerumbet, Alpinia speciosa, Alpinia galanga, Alpinia officinarum.

Common names: Red ginger, Ostrich plume or Pink cone ginger. This species is native to Malaysia.

They are tropical rhizomatous plants that reach 1.5 meters in height. The large and long leaves are deep green. The showy inflorescences have small white flowers surrounded by attractive red bracts. They bloom in summer.

They are used in large pots as indoor and greenhouse plants; in summer they can be taken outside. In tropical and subtropical regions they are used to form groups next to walls.

The Alpinia purpurata needs a semi-shade exposure, receiving 3 hours of sun in the early hours of the morning; the humidity must be medium-high. They do not resist the cold below 14 ºC.

The soil can be a mixture, in equal parts, of normal garden soil, leaf mulch, and coarse siliceous sand.

Water frequently with lime-free water so that the substrate never dries out completely. Place a plate with damp pebbles under the pot and spray the leaves frequently with lime-free water.

Fertilize every 2 weeks in spring and summer with mineral fertilizer for indoor plants.

Prune wilted inflorescences.

They can be attacked by mites and mealybugs if they suffer from drought. They are sensitive to sudden changes in temperature.

They are propagated by rhizome division in early spring.
