The Mammillaria spinosissima “rubrispina” also known as the "Red-headed Irishman" has very attractive copper/red coloured spines at the top of the plant are a rich, coppery-red color. As they mature, the spines fade to silvery white. This globe-shaped cactus has pink flowers..
Mammillaria species like most cacti they're drought tolerant and need very little care and attention to grow well . Plenty of sunshine will keep this cacti more than happy. Provide bright, even light to encourage tight growth and flowering. Some shade during a hot summers day can be helpful to prevent sunburn.
Allow the soil mix to become nearly dry between watering, but then water thoroughly. Suspend watering in the winter, but mist occasionally. Not enough sunlight and over-watering are common mistakes.
Use pot with good drainage and a very porous potting media.
Feed every 4 weeks with a high potassium fertiliser during summer
