We humans may prefer to avoid being blue, but it’s a great look for cacti. Hailing from Brazil, Melocactus azureus (Turk's cap cactus) sports a globular, noticeably ribbed frosty blue body that’s protected by variably colored spines — silvery white to reddish brown.

When the cactus reaches a certain age, fetching pink flowers emerge from its cephalium. Its what? A cephalium is a peculiar woolly mass associated with Melocactus species that forms a distinctive cap of sorts on top of the plant. Far out (or far up, as it were)! Native to semitropical environs, Melocactus azureus is really loving life (best growth & appearance) when the temperature stays above 50° F. Because of that we recommend this one in its own container on the patio or a sunny windowsill. For nifty pairings, locate it near succulents or cacti expressing shades of orange, coral, or light pink.

Part of what makes succulents so fascinating are the myriad ways they express themselves throughout the year, depending on light, season, temperature, soil, and hydration. For those and other reasons, the plants you receive may not look exactly as they appear on our website.
