Gymnocalycium striglianum (Cactus)

This cactacea has a globular stem, slightly depressed at the apex, of a typical purplish almost black color, furrowed by shallow ribs and cross sections that identify the slightly pronounced tubercles. From white and round areoles spines come out that are not very long but visibly robust, of a brownish-black color, which with age tend to fade towards whitish-gray at the tip. From spring to autumn the appearance of this plant is enriched by beautiful bell-shaped flowers, which bloom at the top and remain open for several days, embelleshing the surroundings with their bright colors that vary between pink and red. In addition to being beautiful, it is a perfect cactus for outdoors, as it is highly resistant even to temperatures down to -12 ° C!
