Cactus vs. Succulents

What’s the difference between a cactus and a succulent?

Well, there are two answers:

First of all cactus are native to North and South America, while Succulents grow everywhere.  Second, there is a difference in the way the thorns of the plant are attached.  Cacti thorns emerge from a pad while Succulents thorns are an extension of the body of the plant.

The biggest mistake that I’ve experienced growing cacti and succulents is forgetting that they are plant and therefore have similar requirements to other plants, which is: water, food, air and light.  Cacti and succulents are adapted to fairly extreme conditions but cannot thrive no matter where they are grown, without these vital elements.

Many features of cacti and succulents are adapted to absorb and store water from rainfall when it’s present; so in turn plants can survive throughout the dry season.  These features include a ribbed stem structure to allow for expansion and contraction and a widespread root system for for rapid uptake of water.

Hylocereus undatus is a species of Cactaceae that is one of the most cultivated species in the genus. Pitahaya or Dragonfruit is used as an ornamental vine or a fruit crop.
