Light: What makes this cactus so special, are the wide range of colours on her spines. Find her a home in the sunniest spot you have, then sit back and relax.
Water: Only water once the soil has dried out completely. Once a month is usually enough in our climate. Well-drained soil is a must. We like to water our cacti from the bottom to avoid getting them wet.
Height: Slow growing, she can reach heights of up to 20cm. With the right care, she might flower if you're lucky. Feed with cactus/succulent food during spring/summer.
