shrub with a succulent, medium-sized stem, native to central and southern Africa; this genus has long since faded even in Central America. It has thick and well branched stems, woody in the lower part, cylindrical in shape; the young branches are succulent, of a light green color. The foliage is of very contained dimensions, and develops along the stems, without petiole; climatic conditions such as intense cold or prolonged drought cause a sudden drying out of the foliage, which will be produced again with a more favorable climate. The flowers are produced in the summer are small and insignificant, subtended by small yellow or green bracts. A shrub of euphorbia tirucalli grown in the ground it can reach 4-5 meters in height and as many meters in diameter; the specimens grown in pots generally remain below 100-150 cm in height. If desired it is possible to grow euphorbia tirucalli as a houseplant. When cut, the plant emits a slightly toxic latex if it comes into contact with the skin or mucous membranes.
like most of the plants that develop in a sub-desert climate, this euphorbia also loves sunny locations; more hours a day of sun receives and the more the plant develops healthy and free of diseases or insects. The specimens grown in the apartment should be placed near the windows, so that they enjoy direct sunlight. They fear frost, so in areas with harsh winter climate they need to be cultivated in pots, so as to be able to quickly move the container to a sheltered place when winter frost arrives.
these plants, like mo, the other succulents, are well adapted to drought, and can survive even many days without receiving watering; water only when the soil has been very dry for some days, and only in the period from April to September; we avoid that plants grown outdoors receive water during the cold season.
It is essential to provide the plants with a very well drained soil that does not retain moisture for a long time; a mixture of peat, sand and lapillus is used in equal parts. They can develop even if kept in a container with a small amount of substrate, but it is advisable to change the jar and choose a larger one at least every 2 years.
it happens by cutting; the cuttings of euphorbia tirucalli often not rooted because of the abundant latex they emit, for this reason it is advisable to let the cuttings dry a few days before they are rooted in a soil made up of peat and sand in equal parts.
