CACTUS SPINES: MY MOST AWE-INSPIRING, TERRIFYING & BEAUTIFUL!

This video is a quite prickly and spiny one for a change! It takes a closer look at some of the most stunning cactus spines to be found among plants of the family of Cactaceae (i.e. cacti)! Although we are often drawn to cacti by their amazing, often very delicate and colorful blooms, these plants have another highly characteristic attribute: their often incredibly awe-inspiring, colorful and terrifying-looking spines...hooked, straight, long, short, black, white, red, flat, curved, thick, thin, feathery, etc. - you name it ...and some cacti will have it! To start off, I briefly describe the history and origin of spines, why cacti actually have spines rather than thorns - and I take a quick look at the main functions and purposes of spines. Then I provide stunning and diverse examples of beautiful spines from plants in my own collection - including a feature of some awesome cacti from the genus Ferocactus as well as Trichocereus!
