Alocasia reginula

About

Alocasia reginula, black velvet, is a species of flowering cormous aroid, native to Sabah state in Malaysia. This plant, often referred to as one of the "jewel" Alocasias, became increasingly popular among plant hobbyists between the years 2018 to 2020. Until as recently as 2021 though, not much was known about the plant or its origins. Originally described from cultivation, and often sold as "Alocasia 'Black Velvet'", it is not a modern cultivar or hybrid; A. reginula is its own natural species. It is only known from dry, deeply shaded limestone cliffs in Tabin Wildlife Reserve. As a houseplant it needs sharp drainage or it will very likely rot.
