21:22 All rebutias are beautiful in the spring flowering period, and this quick growing species is particularly good.
The individual heads of this solitary or clustering cactus are globular, sometimes with a flattened top, and reach a height of only 2in/5cm or so.
The short white spines form a neat pattern against the green stem, and in spring each head is surrounded by lV2-m/4-cm-wide crimson-scarlet flowers, which give it its other name, Mexican sunball. In the home, as in its natural habitat, rebutia needs plenty of sunshine, so it will be happiest standing on a sunny windowsill.
