Native to Central Mexico, Thelocactus includes about 15 to 20 species of beautifully spined globular cacti related to Coryphantha and Mammillaria. Some are solitary and some clustering. They range in size from small globular cacti only a few inches around to short columns 8 inches across and 15 inches high. They are prized for their ease of cultivation, colorful spination and showy flowers. The flowers occur in spring and summer and range from white, yellow, magenta and sometimes pink or red.
    Thelocactus are easy to grow in any good cacti potting mix and appreciate moderate water when actively growing. As with most cacti they should be kept drier in winter to prevent rot. Clumping species can be propagated by offsets, all others are raised from seed.
