Golden Barrel Cactus is one of the rare natural plants that grows in a near perfectly rounded shape. Beginning at a size as small as a golf ball in nurseries, this plump golden cactus can grow to enormous sizes of three feet in diameter. With its golden spines spaced evenly around its ridges, it’s a truly beautiful and orderly plant. As a houseplant, which is what Golden Barrel, also known as Mother In Law’s Cushion and Golden Ball, this cactus will not get as big as it might outdoors, but a smaller size will not take away from the stuffing look of this cactus.
While most cacti, including Golden Barrel, grow best in bright, indirect sunlight (full sun windows are great!), they will usually survive even in low light – they just won’t grow much. So if you prefer to keep your cacti at a smaller size, keep them in more shaded areas. They prefer temperatures between 50 and 75 degrees, so watch those window seats when the temperatures turn colder as the windows often will as well. Unlike many houseplants, cacti are not bothered when the heating vents turn on in the winter, so no need to avoid those. Just keep them clear of cold drafts. Golden Barrel Cactus is not known to be poisonous, but it’s spines are very sharp and can cause harm to curious noses and hands. Keeping them out of reach of children and pets is a good idea.
