mostly from the desert lands of southern America,
these plants have a globular growth habit, which tends to become cylindrical over the years. The spines, which are of different colors, may also have the shape and diameter
different in relation to the position in which
Usually those in the middle are more
straight and thick while the side ones
they are slightly arched and smaller in diameter. The flowers, which develop
on the apex of the plant, they are large in size and yellow in color with red shades.
The plants bloom after several years, although some variety soon after
3-4 years already presents inflorescences. They need a lot of light: for this reason the Notocactus resists very well also to the direct irradiation of the sun's rays for several hours a day. However, direct exposure should be avoided during the hottest hours of the day. Like most succulent plants, even this one does not tolerate water stagnation and high humidity levels: for this reason, in winter, water must be limited to what is strictly necessary. These plants tolerate low temperatures quite well, even if the minimum temperature should not fall below 4 degrees. Reproduction is performed through cuttings, seeds or suckers.
