golden barrel cactus

Also known as Golden Ball, Mother-in-Law's Cushion, Mother-in-Law's Chair

Golden barrel cacti form dramatic, ribbed globes armed with vibrant yellow spines that shield the green stem from intense desert ultraviolet radiation. While solitary in early growth, mature specimens eventually produce offsets or clustering heads crowned by a felt-like top where small, bell-shaped yellow flowers emerge during midsummer. Wild populations face severe threats from reservoir flooding and poaching, contrasting sharply with their ubiquity across botanical gardens worldwide.
