Costus louisii is a critically endangered rhizomatous herb from Gabon, known from very few wild collections, so it is rarely grown in cultivation. Its care is inferred from related Costus species, which prefer warm, humid, partly shaded conditions with moist soil.
Costus louisii is a critically endangered species of plant endemic to Gabon.
Costus louisii was first described by Hiltje Maas-van de Kamer and Paul Maas in 2016. A.M. Louis collected the first and only specimen of Costus louisii obtained from the wild. Costus louisii has only been found in a small area, and its habitat appears threatened by human actions.
