Hooveria purpurea is a species of flowering plant related to the agaves known by the common name purple amole.

This species of soap plant is endemic to California, where it grows in the Santa Lucia Range, in the Central Coast region.

[2] The Hooveria purpurea grows in woodland areas of Southern Monterey and San Luis Obispo California coastline.

It grows on highly weathered, rocky, reddish clay soils in foothill woodland areas near the south-central San Luis Obispo County.

It is known from only two locations, the Army installation Fort Hunter Liggett and the National Guard post Camp Roberts.

reducta, is known only from the La Panza Range in the center of San Luis Obispo County, about 61 kilometers away from the nearest population of purple amole.

[2] There is a positive correlation between winter rainfall amounts and the number of purple amole that bear flowers the following spring.

Other potentially damaging forces include gophers, which consume the plants, and feral pigs, which eat the bulbs and trample the habitat.

Camatta Canyon amole occurs in an area used by off-road vehicle enthusiasts and herds of grazing cattle; these two forces tend to damage cryptogamic soil crusts and encourage the invasion of non-native plants.
