globe-shaped cactus that eventually grows tall. Native to Mexico, it bears bright green stems with up to 40 spiked ribs. Contrasting yellow areoles produce golden yellow spines. Bright yellow flowers appear in summer. As a houseplant it works well in a pot as a feature in its own right, or may be grown with other cacti and succulents, particularly those with different leaf colours.
moderate watering during their growing season. Water once every month, from late February onwards (add a little bit of some liquid fertiliser) to boost them
16-18°C during the winter. During spring and summer they can withstand a room temperature of about 20-25 degrees.
