Cactus


It’s already December and cold outside. The hill  in front of our window is covered with snow. At this time of the year I’m usually looking forward to Christmas, but not this year. There is one challenge left I have to face with, and I want to do a good job. Till then here are some pictures of my cacti, which has nothing to do with winter and Christmas, rather with warmth and sunshine. Cacti live in hot and dry environment, so they show many forms of adaptation to conserve water. Most species of cacti lost true leaves, retaining only spines, which are good for defending themselves against herbivores and help prevent water loss by reducing air flow close to the cactus and providing some shade.

Cacti have a variety of uses: many species are used as ornamental plants, others are grown for fodder, and others for food. For example the Opuntia has a fruit known as the prickly pear.

This fruit has a lot of small, barely visible spines, so they need to be handled carefully. Here are some advice:

    • Thank you! This was the first time I tried prickly pear. I wasn’t well prepared, so it took me an hour to get out of my hand those barely visible spikes. :) It wasn’t a good experience, but the fruit was delicious.
