Harrisia regelii grows bushy, scrambling, upright, sometimes arched or prostrate, with green stems that have 4-5 tuberculate ribs. Plants have 1–4 spines, needle-like, initially reddish to almost white thorns later turn gray with a black tip. The individual central spine is 1 to 2 centimeters long. The flowers reach a length of up to 9–22 centimeters with reddish hairs on the buds, spineless and pale green sepals. The spherical, slightly bumpy red fruits have a few scales.[1]

Plants are found growing from Argentina (Santa Fé, Entre Ríos) to Uruguay.[2]
