Myriophyllum mattogrossense 'Golden'

About this plant

Golden is a pale-leaved culture form of Myriophyllum mattogrossense with finely divided, feather-like foliage. Golden, cream and light green tones depend on the growing conditions; a uniformly white appearance is not guaranteed. Cultivators disagree about how demanding it is and whether injected carbon dioxide is indispensable. This profile treats CO2 as helpful, not an established absolute requirement. Give the stems sufficient light and stable nutrition, then judge new tips. Regular topping and replanting maintain a visible fine-textured group without allowing a shaded bare base to dominate. Plant sound shoots with enough space for light and water movement to reach their lower leaves. Use balanced macro- and micronutrient nutrition rather than treating colour alone as evidence of a specific deficiency. Trim established shoots and replant healthy tops to renew an ageing group. Nursery-grown leaves can change shape or be shed after submersion; assess the condition of new shoots and roots. Remove decaying material rather than allowing it to accumulate below the canopy. Care ranges, where supplied, describe reported cultivation conditions rather than measured lethal limits. Width and nutrient concentrations are left unspecified where no defensible form-specific values are available.
