The saguaro is the king of the cactus kingdom. Its large and tree-like shape is very regal in the desert environment. Saguaro can grow for many years and typically get up to 30 feet in height. That said, they’re slow growers. While saguaro are native to the southwest, it’s possible to grow them in warm and/or dry environments. Each pack comes with 10 seeds and basic instructions for germination. I’m a USA seller which means faster shipping times as well as higher quality seeds. A vast majority of my seeds either come from my garden, from my neighborhood or in the local area. If not, I’ve acquired them on trips around the country. I’ve tested and grown many of these myself. I’m always here for assistance with germination and growing. Your success is my success!
