This Myriophyllum keeps its bright, green colour even at very high light intensity. Every stem will only measure approximately 2-3 cm (1”), but it branches willingly and the plant quickly becomes dense and lush.
Cutting down is often necessary to maintain the access to light and water flow. Its moderate growth makes Myriophyllum ‘Guyana’ particularly adapted to nano tanks.
