The peanut cactus is a small charmer: clusters of finger-sized stems covered in soft white spines, multiplying into a low mat that spills over the pot edge. In spring and early summer it surprises people with big orange-red flowers that dwarf the stems themselves.

Give it a bright, sunny windowsill, a gritty cactus mix, and water only when the soil is completely dry, even less in winter. That cool, dry winter rest is what triggers the flower show. Offsets snap off and root easily, so one pot quietly becomes many.
