Cespitose plant with leaves up to two and a half centimetres long, in the shape of a club with a round section, erect and slightly curved towards the interior. The upper part of the leaves, slightly convex, is transparent, free of chlorophyll and allows, like a window, the passage of light to the underlying tissues, when the plant is spontaneously almost buried under the sand. The leaves, towards the base, are reddish.
The flowers are orange-red and appear at the end of summer on three-four centimetre long stems.
The exposure should be bright and sunny, possibly in full sun because in the wild it lives in desert places.
Temperature: in summer the plants must be in the open air; in winter they must be kept in an apartment in rooms that are not too hot.
In winter, watering must be suspended; from the end of February to the late summer, it needs modest watering.
Fertilization: during the vegetative period administer a liquid fertilizer diluted in the water of the watering.
It is sown in spring at a temperature of twenty degrees, then the plants are transplanted into containers with a diameter of 7-8 cm. In summer, multiplication by cutting is possible: the leaves are removed, dried for two to three days and planted.
It is sufficient to place a layer of gravel around the heads of leaves. The containers must be filled with a part of universal soil and a part of fine gravel or coarse sand.
Fenestraria aurantiaca: Pests and Diseases
The red spider causes brown or pale spots to appear on the leaves. If the atmosphere is too dry, the plant appears weak or withered: it is advisable to spray the leaves often. Lack of light can lead to a lack of flowering, weakening of the stems and dull colouring of the leaves that bend laterally.
