Tephrocactus is a fascinating group of South American cacti recognised for its unusual, jointed growth. Rather than forming one continuous stem, these plants develop rounded or cylindrical segments that can appear loosely stacked or clustered together. Their textured bodies are often covered with fine spines or glochids, giving them a rugged yet sculptural character. Some varieties produce attractive flowers in white, yellow, pink or reddish shades. Their segmented form, compact growth and distinctive appearance make Tephrocactus an appealing addition to specialist cactus collections..
