Guarianthe aurantiaca
Guarianthe aurantiaca, the Orange Cattleya, is a pseudobulbous epiphytic orchid from Mexico to Costa Rica that grows on trees in humid tropical forest. Grow it mounted or in a fast-draining orchid mix with bright light, regular watering while growing, and a dry rest period after new growth matures.
Guarianthe aurantiaca is a species of orchid. It is widespread across much of Mexico, south to Costa Rica. The diploid chromosome number of G. aurantiaca has been determined as 2n = 40.
The phananthrenoids orchinol and loroglossol have a phytoalexin effect and reduce the growth of G. aurantiaca seedlings.
