Myriophyllum mattogrossense

Myriophyllum mattogrossense is a beautiful feathery-leaved stem plant from South America with very fine, pinnate leaves arranged in whorls around upright stems, creating a soft, almost misty texture that is highly valued in planted aquascaping. Its delicate appearance provides a striking visual contrast to broad-leaved plants and a soft backdrop texture when planted in groups in the background.

It is a moderately demanding plant requiring bright light and CO2 injection for compact, well-structured growth. Without CO2 the fine leaves can deteriorate and growth becomes sparse and unsatisfying. A nutritious substrate and regular liquid fertilisation with trace elements support healthy, consistent development. Hard water and high pH can inhibit performance.

Supplied as an established potted plant, Myriophyllum mattogrossense suits aquariums from 60 litres upward with bright lighting and CO2. Planted in dense groups in the background, the whorled feathery foliage creates a rich, textured backdrop that forms a dramatic contrast to foreground carpeting plants and midground rosette species.
