Myriophyllum Guyana
Myriophyllum Guyana
Myriophyllum Guyana is a delicate South American Myriophyllum from Guyana producing particularly vivid, bright green fine-leaved foliage with an almost luminous fresh-green quality that makes it an exceptional contrast plant in the background of planted aquariums. The bright, nearly lime-green color is more vivid and fresh-looking than standard mattogrossense or other green Myriophyllum forms — an unusually luminous green quality that stands out in any background composition.
Care tip: Myriophyllum Guyana grows best in moderate lighting with CO₂ recommended. Maintain temperatures of 70–82°F and pH 6.0–7.5. Regular liquid fertilization supports healthy growth and best coloration.
Growing to 12 to 18 inches, Guyana is a background plant that rewards regular trimming with lush, vivid-green growth. The bright color is most vivid in actively growing new stem tips — regular pruning cycles keep this most luminous growth consistently prominent in the composition. Without regular trimming, the lower portions of older stems become shaded and lose the characteristic bright green quality.
This moderate plant grows in moderate lighting with CO₂ recommended. Temperatures between 70 and 82°F and a pH of 6.0 to 7.5 provide comfortable conditions. Regular fertilization supports the vigorous growth and the distinctively vivid green color. As a fast grower, consistent fertilization is particularly important for maintaining the luminous color quality throughout the delicate foliage.
In the aquascape, Myriophyllum Guyana provides a luminous, bright green background accent whose vivid color creates natural visual freshness alongside warm-toned reds and oranges. Against red Ludwigia, Alternanthera, or Rotala the almost lime-green color of Guyana creates one of the most dramatic cool-warm green-red color contrasts available from a feathery-leaved plant. It is most effective as a featured background accent or transitional zone between warm and cool-toned plant sections.
Myriophyllum Guyana is a vivid, luminous green background plant for aquarists who want the brightest possible green in a fine-textured feathery form. Its almost lime-green color and fast growth make it an excellent and practically useful contrast plant in any warm-toned planted aquarium background.
