The numerous species of cacti in Saguaro National Park were a wonderful sight to see. Some of these species can be seen in this image. The long spines of the ocotillo plant stand out and provide a pleasant variation in the texture of the landscape. This species can grow to over 30 feet in height, which is taller than many plants, but cannot outdo the giant saguaro. A lone saguaro cactus can be seen at the left part of the image and, although not as large as a full grown version of the species, it cannot be considered a young plant. Saguaros are very slow growers and may live for more than 150 years. Although the largest known saguaro was nearly 80 feet tall, most of the adult specimens we saw in the park were likely around 30-40 feet in height, still a very impressive sight. Also seen scattered across the landscape is the prickly pear cactus with their flat, rounded, pads. Between two large ocotillo plants in the center-back of the image, a staghorn cholla can be seen. There is also a buckhorn cholla in the right-bottom of the photo, in front of one of the ocotillo plants, which appears as a relatively small, spiny, bush. There is a barrel cactus that is harder to spot; it is low to the ground and a bit in front of the saguaro at the very left edge of the frame. All of these unusual looking plants, and the other cacti species that call the park home, are wonderful to observe, especially up close and in person (just not too close).
