The flowering species Plectranthus forsteri and Coleus blumei, stand out with their compact foliage, particularly decorative and a high degree of coverage in a short time. This paper aims to study the behaviour of these species in vertical systems for green façades, in the climatic conditions of North East part of Romania. The vertical experiment was set up on the façades of an experimental module built specifically to test the strength and adaptability of several ornamental species in this system. The experimental structure was made of height levels that were applied on the four facades of the module oriented towards the four cardinal points. A ground control variant has also been set up. The study found that Plectranthus forsteri and Coleus blumei grown in vertical systems for green façades show high adaptability regardless of the cardinal orientation. On the ground, Plectranthus forsteri behaved well, creating a compact and uniform layer unlike Coleus blumei which had a more modest behaviour in the experience.
