The flowering of this species was the subject of a festival ("Festival de Amancaise") celebrated in June in Lima, until the first half of the 1800s.[12] In a place among the hills surrounding Lima, people from the city gathered annually to celebrate the flowering of the plant in a festival with music and dance, similar to May Day.[12] The festival attracted people from all classes of the society then, while a common sight was people sporting the flowers in their garments.[12]
