Its blue-green, covered with grayish wax. Branches erect, parallel to each other, all almost the same length, curved at the base, with the apex attenuated,up to 10 meters long and 5–15 cm in diameter. The cactus has 5–8 bluntly triangular ribs up to 2 cm high, and its ]s merge with age. It features 1–4 yellowish-white central spines up to 5 cm long and 6–9 shorter reddish-brown wool and some short, bristly radial spines that darken over time, reaching 1 cm in length.

The scentless tubular flowers grow near the shoot tips and bloom multiple times, sometimes forming small crowns.
