The Sand Dollar Cactus, also known as Star Cactus or Sea Urchin Cactus, is a distinctive, spineless succulent with a perfectly round, flattened shape. Its deep green body is divided into symmetrical sections, often adorned with small white dots and tufts of golden fuzz, giving it a star-like appearance. This rare and slow-growing cactus is a prized addition to any collection, bringing a touch of desert beauty in a compact form.
