Red Myrio

Red Myrio

Red Myrio is a North American Myriophyllum that develops warm reddish tones at the growing tips and upper portions of stems under high light and CO₂ — creating a uniquely fine-textured warm-colored background plant whose feathery texture combined with red coloration provides a visual quality unavailable from any broad-leaved red stem plant. The red intensifies progressively with improving conditions, scaling naturally from green-reddish under moderate conditions to vivid red tips under excellent high-tech parameters.

Care tip: Red Myrio grows best in moderate to high lighting with CO₂ recommended. Maintain temperatures of 68–82°F and pH 6.0–7.5. Regular liquid fertilization supports healthy growth and best coloration.

Growing to 12 to 24 inches, Red Myrio is a vigorous background plant that responds well to regular trimming to maintain compact, well-colored growth. Regular pruning cycles ensure the most vividly red new growth is always the prominent visual element of the planting. Without trimming, lower portions of older stems lose the red coloration and become plain green as the upper canopy shades them out.

This easy plant grows in moderate to high lighting with CO₂ recommended for the best red expression. Temperatures between 68 and 82°F reflect the broad thermal tolerance of this North American species. A pH of 6.0 to 7.5 provides comfortable conditions. Iron-rich fertilization supports the red pigmentation in the feathery leaves. Regular trimming is essential for maintaining vivid color throughout.

In the aquascape, Red Myrio provides fine-textured warm-toned background coverage whose feathery red foliage creates a different visual quality from the bolder, broader-leaved red stem plants. The fine texture allows depth and light penetration through the background zone that creates a more naturalistic, dimensional red background than solid-leaved species can achieve. It pairs beautifully with green Myriophyllum in the same background for natural color contrast within a unified texture register.

Red Myrio is a fast-growing, fine-textured, and practically accessible warm-toned background plant for aquarists who want red color in a feathery, naturally textured form. Its color scaling with conditions and easy care make it a versatile and rewarding background species across a range of planted aquarium setups.
