On a previous entry I wrote about the practice of gluing fake flowers on cacti . If you're not aware of it cacti and succulents growers glue straw flowers on cacti when they aren't blooming in order to increase sales of these plants. Those pink, green, red and blue flowers you see growing on cactus in the big box stores are indeed fake. The most common cactus that you'll encounter decorated with the the straw flowers is one that is referred to as "Fairy Castle Cactus."
