Echinomastus is a small, hardy genus of cacti native to the southwestern United States and northern Mexico, known for their compact, rounded bodies and distinctive, often ribbed surfaces covered in dense spines. These resilient plants typically produce striking, brightly colored flowers in shades of yellow, orange, or red during their blooming season. An interesting fact is that Echinomastus species are well-adapted to harsh desert environments and are prized for their impressive blooms and easy care, making them a popular choice for desert plant enthusiasts.
