I have assembled a list of some cool looking cactus types I enjoy. Have fun reading!
This cactus grows into the shape of a star. Found in Africa, it blooms in the Springtime. If you wanted to grow it here in Canada, you need to allow it to live in a room that has a constant temperature of about 36 degrees.
This cactus grows generally around the coastal plains in Mexico. Similar to the the Aloe, this cactus grows best in spring, and requires temperatures hovering around 32 degrees. Is susceptible to frost, so be wary come winter.
