Previously known as Trichocereus spachianus for many years, it is commonly cultivated as a pot or rockery plant worldwide.

It has a columnar habit, with a lime-green cylindrical body with 1–2 cm long golden spines.

Soehrensia spachiana grows as a cactus with a columnar habit, reaching 2 m (7 ft) high, with a diameter of 5–6 cm (2–2+1⁄4 in).

[4] French botanist Charles Antoine Lemaire described the species as Cereus spachianus in 1839, in honour of his countryman Édouard Spach.

However, a 2012 genetic analysis of chloroplast DNA indicates Echinopsis is made up of several divergent lineages.
