Description: Echinopsis obrepanda var. purpurea are presumed natural hybrids derived from crosses between a member or members of the obrepanda group and one or more unknown lobivias. (Perhaps Lobivia mizquensis, Lobivia pojoensisSN|21066]]SN|21066]] or other similar species, Both with red flower and regarded as varieties of Lobivia calorubra).
Remarks: This hybrid forms are often listed as subspecies of Echinopsis obrepandaSN|21037]]SN|21037]] but the mixtures of Echinopsis/Lobivia characteristics in virtually all of the presumed hybrids is a good indication that they do have a hybrid origin.
The intermediate-type characteristics are:
Throat lengths: Short in the lobivias and long in the Obrepanda group.
Flower colour: Red in the lobivias and white in the Obrepanda group.
Throat colour: Red in the lobivias, light greenish in the Obrepanda group.
Rim stamen colour: Red in the lobivias and white in the Obrepanda group, and
Throat stamen color: Red in the lobivias, distally white and light green basally in the Obrepanda group.
This hybrids can be easily distinguished From Echinopsis by their colored flowers and by their rib tubercles, most of which are hatchet-shaped at least in the apical portions of the stems.

Cultivation and Propagation: The Violet Easter Lily Cactus is a summer grower species that offers no cultivation difficulties. Water regularly in summer (but do not overwater ) needs good drainage and very porous soil, keep rather dry in winter. Feed with a high potassium fertilizer in summer. It is quite frost resistant if kept dry (hardy to -7° C). Need a bright exposure, full sun or half shade in summer.
Propagation: Direct sow after last frost, offsets.
