Christmas Moss Variant care guide
Christmas Moss Variant (Vesicularia montagnei) — low light, 18-28 °C, pH 5.5-7.5, no CO2.
Overview
Christmas Moss Variant (Vesicularia montagnei) is a moss of the family Hypnaceae, grown as an aquarium plant. A delicate moss with triangular fronds that drape downward in overlapping layers, closely resembling miniature Christmas tree branches. Grows more compactly than standard Christmas Moss and attaches readily to hardscape, making it ideal for detailed aquascaping work.

- GH: 2-12 °dGH
- Substrate: not applicable (epiphytic attachment to hardscape)
- Maximum height: 5 cm
- Growth rate: slow
- Nutrient demand: low
- Recommended placement: epiphyte on wood or rock

Placement
In aquascapes this plant grows as an epiphyte on wood or rock.
Propagation
Propagation is by division of the parent clump; daughter plants are separated once they have formed several leaves and visible roots.
Common issues
Pale or stunted new growth usually signals a nutrient or iron deficiency, while algae on older leaves often follows light that exceeds the available nutrients or CO2; correcting fertilisation and trimming affected parts resolves most cases.
