It is a large, solitary, ribbed barrel cactus that turns cylindrical in age and reaches an exceptional height of 3 meters. Its stem is unbranched, dark green, first globular and then cylindrical, erect, up to 1.5 m or more in height and up to 30 m wide. The ribs between 16 and 24 are prominent, sharp, slightly tuberculated and expanded below the areolas, 2 cm. tall. Young light gray felt areolae, oval to elliptical, 15-20 mm long and 6 mm wide, constricted between the flower and the carrier section of the spine, 4 cm or less apart in older plants. The spines are clearly differentiated into robust centrals and thin, white rays. The central spines 7 to 13 in two series, reddish with yellow, grayish or brown tips, with bands, somewhat curved, twisted and tangled, annulled, the main 4 form a cross, flattened upper and lower, two lateral subulates, the more lower long, less than 7 cm long and between 6 and 10 mm wide, quite convoluted and curved or reserved at the tip. The radial spines between 8 and 12 are whitish, extended, up to 6 cm long, variable, slender, straight, flattened-setaceous, sometimes twisted, three lower striae acicular to the subulate. The funnel-shaped flowers, approximately 4 cm long and 3.5 cm in diameter, reddish with darker red veins. Ovary with widely placed scales that intersect in obtuse, red, external perianth segments. Internal segments of the linear-lanceolate internal perianth 25 mm long and between 5 and 7 mm. wide, medium lavender red, yellow margins, serrated. Numerous, fine filaments, compressed against style. Style 22 mm long, yellow and red above, stigma lobes 9. Flowering season: Plants generally flower in late spring or early summer, occasionally in late summer. Solitary bees are probably the most important pollinators. Ants visit extrafloral nectaries at the apex of the plant and can protect the cactus from insect herbivores. The fruit is oblong, cylindrical, yellowish, 2.5 cm long, with broad, rounded scales, without dehiscence through basal pores. The seeds are rounded, somewhat angled, irregular and slightly larger than that of the gracilis,

They need a lot of light to develop their typical spine, but different clones vary in their tolerance to full sunlight.
The lowest temperature (ºC) supported by this cactus is on average:: -2

During hot weather you may need to water the plants more frequently as long as the plant is actively growing. From autumn it should be reduced.


Mealybugs, scaly insects and mites. Watch out for rot if the plants are over-watered

It grows well in rich, well-drained soil, such as clay, pumice, lava sand, and just a little bit of peat or mold, but is not demanding on the soil.
