Description: Echinopsis oligotrichaSN|13648]]SN|9465]] (syn: Lobivia cinnabarinaSN|9455]]SN|9455]] subvar. oligotricha) is similar in habit to Echinopsis cinnabarina var. acanthoplegmaSN|9465]]SN|13648]] but the flowers tube are typically nearly naked (or with few hairs). It is a small plant with flattened stem, but worth growing for the fantastic pink-violet to red flowers with a contrasting white throat. As most Libivias it is easy to grow and ready flowering plant.
Habit: It is a small, low growing cactus that grows usually solitary (unless damaged).
Stem: Green, spherical-flattened to spherical, 15 cm diameter.
Ribs: Approx 26 with noticeable tubercles up to 15 mm long.
Radial spines: Approx. 10, up to 20 mm long, awl-like, lying flat to the body, more or less interlaced.
Central spines: Usually absent.
Flower: Arising from the basal tubercles on the side of the plant, up to 5 cm long and in diameter, unscented, pink-violet to red, throat usually lighter or white.
Fruit: Globose to oval, semi-dry and perpendicularly splitting.
Seed: Spherical, rough, grey, covered with skin remainders.

Cultivation and Propagation: Echinopsis oligotrichaSN|9465]]SN|9465]] is a summer grower species that offers no cultivation difficulties. Water regularly in summer (but do not overwater ) needs good drainage and very porous, keep rather dry in winter. Feed with a high potassium fertilizer in summer. It is quite frost resistant if kept dry (hardy to -12° C). Need a bright exposure, full sun or half shade in summer.
Propagation: Direct sow after last frost, offsets (if available).
