By this method the juvenile stage is suppressed and, in a year and a half, its flowering can be obtained. Thus, it is possible to enjoy beautiful flowers from spring to winter.

Fun Facts About Cactus Flowers
How long do cactus flowers last
The truth is, very short.
The flower of a cactus is made to be attractive to pollinators, which are very scarce in their natural habitat, and also to last little.
It will usually last a few hours to a maximum of one or two weeks, the least lasting being those of the Echinopsis or Lobivia, and the most durable those of the Discocactus, Coryphanta or Astrophytum.
Types of cactus flowers
Cactus flowers are very beautiful, with cheerful and very decorative colors such as red, pink, white or yellow. But, depending on its shape, we can distinguish three types:
They are the most characteristic flowers of cacti, and some of the most spectacular. The genera Rebutia, Lobivia or Echinopsis are the ones that produce the most showy flowers. They can measure up to 4cm in diameter .
There are some cacti, like the Mammillaria, that produce very tiny flowers that barely separate a little from the mother plant. They measure less than 1 centimeter , but their ornamental value is very, very high.
Like those of the Cleistocactus or the Oreocereus for example. These types of flowers are kept closed, only the stamens and pistil emerge a little outside . They are the ones that attract the least attention, but they are very curious. And it is that living in areas where at night the temperature drops to close to 0 degrees, and even more, if they want to multiply they need the most sensitive parts of the flower to be protected as much as possible.
