The Stromanthe sanguinea is an evergreen herbaceous plant native to South America; it has creeping, fleshy rhizomatous roots, which produce large heads of leaves, carried by a long rigid, fleshy stem; they are 15-30 cm long, thick and rigid, dark green on the upper page, purple red on the lower page. In spring, they produce erect stems, tall up to 50-60 cm, which carry small ears of pink or white flowers, very particular. S.
sanguinea ‘Tricolor’ has variegated leaves, of dark green, white and pink colour. These plants are very decorative throughout the year, very suitable in bright corners of the house. However, these plants are not too easy to grow: in fact, they need humid environments both during the summer and winter seasons to grow at their best.
As these plants are very sensitive to temperatures, we should pay particular attention to the position in which we place the pots in the house. Exposure is an essential element to take into account if we want to grow these species in the best possible way. Store the Stromanthe sanguinea in a shady, but bright place, never directly exposed to sunlight; during the season they can be placed outdoors, in the shade.
From March to November, water regularly, trying to keep the soil constantly moist, during the cold months thin out watering, letting the soil dry slightly, we recommend that you spray the leaves often to increase the humidity environment. During the vegetative period, provide fertilizer for green plants, every 25-30 days.
During the whole year, the most important aspect to consider is precisely the humidity of the environment in which your Stromanthe lives: humidity is the essential condition for the development of this species.
They are cultivated in soft, light, rich of humus, very well drained soil; it is possible to prepare an ideal soil for these plants by mixing some universal soil with a few chopped bark and some handfuls of pumice stone. The repotting takes place every year during the spring season. It is necessary to use a larger and deeper container to allow the plant to develop its root system.
During the spring and summer, it is recommended to give liquid fertilizer together with the water of the watering to help the plant to grow at its best! As far as pruning is concerned, it is usually not done because there is no need to cut or shorten the branches. Only remove damaged or dry parts, which are often the primary cause of the development of fungal diseases.
Rhizomes tend to constantly produce new small plants, which can be separated from the mother plant and repotted as individual specimens; this operation is preferably done in autumn and is known as multiplication by division. For this operation, use clean, disinfected and well-sharpened work tools in order to make clean cuts and avoid fraying.
