It has the typical rosette shape, well recognizable, compared to other genera, for the strongly pointed leaves, which are of the shades tending to dark green or grayish. They are quite resistant succulents that, unlike others, adapt well to low temperatures: for this reason they are often used to decorate gardens, as well as indoor spaces all over Italy! Here are some tips for its cultivation: It requires a lot of light throughout the year, however, avoid direct sun rays, especially during the hottest hours of the day, as long as they might burn the leaves.

They do not need frequent fertilization, it is sufficient to dilute the fertilizer with watering once a year.
