The Cactus Flower - I have seen a innumerable variates of Cactus Trees, but none that looks like a Flower. This very peculiar little Cactus Flower Tree, resembles to any flower, but the peculiarities are many. Though it looks like a flower, it is actually a tree, but without any stem or leaves for that matter. These Cactus flower lasts for a long time, but they don't have any peculiar smell/fragrance, like the general flowers that we come across. Once it starts growing up, it spreads horizontal to the earth, unlike the general shrubs. It hardly grows to a height of less than 6 inches, and doesn't come in many shapes and colors. It's greenish cactus color attracts our attention.
