some columnar cacti, originating in South America, also present in high altitude areas belong to this genus. They have erect stems, 6-7 m high in nature, dark green or bluish in color, with numerous little pronounced ribs; they tend to branch in the upper part of the stem, sometimes producing a dense crown of intertwined branches. The young stems have areolas with numerous spines, which the plant tends to lose over the years. In summer it produces large tubular flowers, white or pink in color, which bloom at night; the chalice and ovary are covered with leathery flakes. In late summer the flowers are followed by large oval, pulpy fruits, containing many seeds of reduced size.
these plants need to be planted in very sunny locations, which receive at least 5-6 hours per day of direct sun; browningies fear temperatures below 0 ° C, to avoid damage caused by the cold, they are grown at winter temperatures not lower than 8-10 ° C.
