Thelocactus bicolor (Galeotti ex Pfeiff.) Britton & Rose
This cactus is also commonly known as "Texas glory", to indicate, how the populations of these areas are proud of the origin of this currently widespread plant.
It has a solitary greyish-green stem of a slightly ovate shape, equipped with wide and tuberculous ribs, sometimes arranged in a slight spiral.
The characteristic, for which they became so popular, are undoubtedly their long colorful spines, which range in color from yellow to red.
Another very important feature are their rather large, bell-shaped inflorescences, that bloom at the apex, generally also of a double color, with a throat of a more vivid color, rather than that of the ends; each petal is characterized by an extremely silky sheen.
- It likes an exposure to full sun in rather airy locations.
- It is preferable to keep it at mild temperatures and never below 4 °C, for this reason it is recommended to place it in sheltered and ventilated locations 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.
- The best option is a soil suitable for cacti, 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.
