Columnar cacti originating in Brazil and South America. They have quite thin stems, little branching, erect, bright green, sometimes bluish, and carry many spines clear, very sharp and thin; great openness of the species is kept below 50 cm, but some species can reach even one meter.
When ripe, they produce at the apex of the stems of the flat cephali, formed by a thick reddish down, erect and rigid; in summer, from the cephalium, many fleshy and waxy flowers bloom, tubular, of pink, yellow or red colour, depending on the species, often united in small groups; in late summer, these plants produce small elongated fruits, of a bright colour. In general, the plant continues to grow even after producing the cephalium, from which flowers will bloom for 2-3 years.
During the hot months it is best to place the arrojadoa in a semi-shady place, avoiding direct sunlight; in winter place them in full sun in a sheltered place, with a minimum temperature of not less than 10°C.

From March to October, water every time the soil is dry, at least once a week; with the arrival of the cold, thin out the watering, almost to suspend it in winter. During the vegetative period, provide the plant with specific fertilizer for succulent plants, mixed with the water of the watering, every 15-20 days.
prefer very well drained soils, consisting of universal soil mixed with river sand and pumice stone, with a fairly small particle size. The plants cultivated in very small containers tend to have a lower development than what is expected in the wild.
takes place by seed; in late spring it is possible to make apical cuttings, which root with great facility if they are buried after aevr made to dry up well the wound.
