Its name was given in honor of the Argentine pharmacist Domingo Parodi. This genus was initially very homogeneous, only later new plants of various shapes were merged, therefore it now includes small spherical cacti with depressed apex, but also columnar, solitary or clustered ones, with well-marked ribs or with very different tubercles and spines. However, all the species have in common the enchanting funnel-shaped inflorescences, that in summer bloom in abundance at the apex of the cactus. These plants will give a touch of color and freshness to your home, if you give it just a bit of attention and simple care! Here are some tips for its cultivation: It likes very bright positions, however avoid direct sunlight during the hottest hours of the day. It is preferable to keep it at mild temperatures and never below 8 °C, for this reason it is recommended to shelter it during the winter period. Water moderately, only when the soil is completely dry. It is enough to water the plant once a week in spring and summer, once a month in autumn and to suspend watering completely in winter. A soil suitable for cacti is an optimal solution, even better if further mixed with pumice or lapilli. They do not need frequent fertilization, it is sufficient to dilute the fertilizer with watering once a year.
