Lantana flowering at an indoor active living wall in a light-restricted environment

Abstract

The time spent by urban residents indoors has been increasing annually, thus, prioritizing the enhancement of indoor spaces into green spaces to improve the quality of life. Even with limited environmental conditions indoors, an active living wall and LED light techniques have enabled us to explore indoor green environments. In the present study, the yellow/orange-colored flowers invasive ornamental species, Lantana camara ‘splendens’, was cultivated in 4.0 m2 of the active living wall under a non-decorative LED lamp, adjusted to optimize performance in the coverage area. This study evaluated the development of lantana in the active living wall under different light intensities (135 watts and 90 watts) in a room with light restriction. Parameters such as plant height, flowering, SPAD chlorophyll content, and vegetative cover were analyzed. The results indicated that Lantana camara ‘splendens’ is suitable for use in active living walls and blooms at a low light intensity when the light is uniformly applied.
