Clusia rosea


GeneralitŠ°


The Clusia genus includes about 150 species of shrubs and trees originating from the tropical areas of America; c. rosea in nature is a tree of small or medium size, while the specimens grown in pots maintain the size of small shrubs, not exceeding 150-200 cm in height. They have broad and well branched stems, the branches are thick and robust, generally they develop with their tips pointing upwards; the foliage is evergreen, oval, quite thick and leathery, each leaf measuring about 10-15 cm in length and is dark green, shiny and bright. During the spring months they produce large semi-double flowers, which resemble large camellias; as soon as they bloom the flowers are white, they become pink with the passing of days, and give off a pleasant scent; the flowers are followed by oval, greenish, yellow or orange fruits which, when ripe, open up in numerous segments, taking on the appearance of large stars, and showing the small seeds inside, covered with a striking red aril. In the areas of origin these trees are also used as ornamental plants and in urban furnishings, even in areas subject to strong winds. In Europe these are plants grown exclusively in pots, although they could withstand outdoor cultivation, in a place protected from the cold, in southern areas.

Exposure



During the cold months the clusia rosea should be kept in the apartment, in a bright place, but not directly exposed to sunlight; the direct rays of the sun could dry out the leaves of the clusia rosy. In the warmer months they can be moved outdoors, in a semi-shaded place.

Watering



The specimens grown in pots need a constantly moist soil, although it is advisable to avoid excesses, and to reduce watering during the winter months; in fact, the clusias can also withstand periods with non-ideal humidity conditions, therefore both short periods of drought, and short periods of soil very soaked with water. From March to October it is advisable to supply fertilizer for flowering plants, mixed with the water used for watering, every 12-15 days.

Ground


these plants need a very soft and loose soil, quite rich in organic, well-drained matter; often in nature the clusia specimens have an epiphytic development, and produce long aerial roots that only with the passing of the years tend to develop towards the ground. Generally, a good balanced universal fertilizer is used, mixed with a small amount of soil for orchids, consisting of bits of bark and other incoherent material. Every two or three years it is advisable to repot the clusias during the spring period.

Multiplication



The reproduction of clusia rosea occurs by seed, using the seeds extracted from mature burps; in spring it is also possible to take apical cuttings, taking care to choose the branches that will not produce flowers.

Clusia rosea: Parasites and diseases


In case of dry and poorly ventilated climate they can be attacked by the cochineal; if grown in poorly draining soil or with stagnant water they can be affected by root rot.
