Mammillaria Elongata
Mammillaria elongata
📖 About this plant
Mammillaria elongata, commonly known as Lady Finger Cactus or Golden Stars Cactus, is one of the most charming and easy-to-grow cacti available. It forms dense, low mounds of hundreds of thin, finger-like stems that are completely covered in soft, star-shaped golden-yellow spines, giving the entire cluster a fuzzy, golden appearance. The spines are relatively soft compared to many cacti, making it one of the more touch-friendly options. In spring, each stem tip produces a crown of tiny creamy-white flowers that can nearly cover the entire cluster. It readily produces offsets, quickly forming spectacular golden mounds.
