The single species A.distichum, native to Korea, is classed as endangered in the wild, and at high risk of extinction. Cultivation of the wild form especially is therefore a valuable conservation safeguard. Its fragrant flowers in spring attract bumblebees and butterflies that need to feed on their emergence from hibernation.
