Care guide

Overview

Narrow lanceolate leaves form a low, ivy-like carpet in olive green, developing a grayish-purple to silvery-pink cast under strong lighting. It spreads by runners and cuttings but grows more slowly than Staurogyne repens, wanting medium-high light, CO2, and a nutrient-rich substrate to knit into a dense foreground lawn rather than stretch upward.

Care

A low creeping plant that hugs the substrate in a manner similar to ivy, making it a reliable choice for filling in the foreground of an aquascape. It grows more slowly and is somewhat fussier than the closely related Staurogyne repens, doing best with medium to high light, a rich substrate, and supplemental CO2. Given weak light or poor nutrients it tends to stretch upward instead of spreading, so keepers aiming for a dense mat should prioritize even light coverage over intensity alone.

Planting & trimming

Plant small clumps a couple of centimeters apart in a grid across the foreground so the individual portions knit together into a continuous carpet over time. Push roots gently into the substrate and weigh or pin them down until anchored, since loose portions tend to float in the early weeks. Trim across the top periodically once established, since cutting the entire group encourages lateral spread and hides the trimming line better than removing large chunks at once.

Fertilizing

Root tabs pushed into the substrate around the base support steady growth, and a balanced liquid fertilizer dosed weekly helps sustain the carpet once it fills in. Iron supplementation intensifies the grayish-purple sheen that develops on the leaves under strong light. Yellowing leaves or stalled growth usually point to a nutrient shortfall rather than disease, and are best corrected with more consistent dosing.

Propagation

Propagates readily from head cuttings and side shoots produced after trimming, which can be replanted directly to thicken the carpet. Established mats also spread via runners along the substrate, and mature clumps can be lifted and split into smaller sections for replanting elsewhere in the tank.

Problems

New plantings often shed a few older leaves while roots establish, which is normal and not a sign of failure. Algae fouling on the leaves is the most common complaint and typically traces back to excess light relative to available nutrients or weak flow across the carpet. Reducing photoperiod slightly, increasing fertilization, and improving circulation usually resolve the issue without needing to remove the plant.
