👉 Saguaros are a genus of about 30 species of flowering plants in the family Sapindaceae, native to South America. They are known for their distinctive, needle-like leaves and their ability to produce large, succulent fruits known as sapirs, which can grow up to 2 meters tall. Saguaro cacti are particularly well-known for their unique shape and color, which is often described as "scintillating" or "stunning".
