Saguaro are magnificent cactus and – in my opinion anyway – no two are exactly alike. Some are just straight up and down without arms (known as spears) while others grow side arms. They have an incredibly long life span with some not growing a side arm until they reach 75-100 years in age and they can reach a height of 70 feet tall. So having that bit of information as background material one can only guess how old this beauty is with it’s arms upon arms.
