Blooming Spider Cactus
If I don’t have my eyeglasses on while tending to my cacti, I would see a bunch of small white spiders creeping on my Gymnocalycium denudatum. I would often confuse the spines for bugs attacking the cream-white flowers. Well, I guess that is why they obviously call this succulent as Spider Cactus due to the way its white spines look like — spider legs that cling close to the body of the plant. (See the photo below.)
The dark green body of my Spider cactus is glossy and globular, about 4 inches tall and 3 1/2 inches wide. It is “slightly chinned” and has eight rounded ribs. Each spines are about a centimeter long and not injurious.
The Spider Cactus is very easy to grow. It requires full sunlight, enough water and a dose of fertilizer to yield cream-white flowers with some rosy tinge at the edge. Depending on the size of the cactus, the flowers are about 5 – 7 cm wide.
