Cacti can be much more than just prickly. Plantura introduces you to the different types of cacti so you can make the best choice.
The mostly prickly succulents are perfectly adapted to their environment. The cactus family (Cactaceae) has invaded areas where no other plant could thrive, proving that life can survive in the most adverse conditions. However, the external appearance of these botanical wonders is at least as extraordinary as their habitats. From miniature figures to meter-high columnar cacti: - Cacti fascinate with their almost extraterrestrial uniqueness, of which there are up to 1,800 species in abundance. We'll take you on a little excursion into the world of cacti and show you a selection of the most beautiful species.
Cactus species: diversity and characteristics
As with every family, the cactus family (Cactaceae) has a few unmistakable similarities. All but one species are native to the Americas. Here, the perennial survivors have conquered a niche in a wide variety of habitats. From steppes to rainforests - the mostly succulent plants are represented everywhere. Only the seasonal availability of water is common to every environment. Because here the cacti have a clear advantage due to their ability to store water in their succulent trunk and leaves. In addition, all cactus species have so-called areoles (greatly reduced short shoots). In seedlings, the aeroles always bear felt and spines formed from transformed leaves. Depending on the species, these are kept or discarded even when they are adults. The leaves, if any, also have their origin here. Apart from that, the bizarre growths couldn't be more different:
- Growth: from 1 cm to 20 m
- Growth Form: Trees; flat; geophytes; spherical; Shrubs
- Growth: Upright; aspiring; creeping; rarely hanging
- Growth rate: from 1 m per year to hardly any growth over the years
- Roots: Succulent beets, fibrous or succulent tubers
