Cryptocoryne nurii (Heart-leaf Water Trumpet)

03 October 2026

283

Cryptocoryne nurii is a small, slow-growing rosette plant from Asia, valued for its textured, often wavy leaves and tolerance of subdued aquarium lighting. The supplied label supports identification as C. nurii, although the exact cultivated form cannot be confirmed from the available material. It is best planted in the foreground or middle of a mature aquarium and should be disturbed as little as possible after planting.

Cryptocoryne nurii (Heart-leaf Water Trumpet)

Identification

The supplied product label names the plant Cryptocoryne nurii. Its compact rosette, narrow lance-shaped leaves and strongly textured or wavy surface are consistent with that identification. Cryptocoryne species can vary substantially between populations and cultivated forms, so the precise variety or locality cannot be determined here.

Placement and planting

Plant the roots in nutrient-rich sand or fine gravel while keeping the crown above the substrate. A small group can form a low, structured planting in the foreground or middle ground. Avoid burying the crown, and leave enough space for the rosette to expand.

Water and lighting

Use stable, clean aquarium water with gentle circulation and low to moderate light. It generally benefits from soft to moderately hard water and mildly acidic to neutral conditions, but gradual acclimation is more important than pursuing a narrow target range. Avoid abrupt changes in temperature or water chemistry.

Nutrition and carbon

Root-zone nutrition is useful because this plant feeds substantially through its roots. Add a controlled substrate fertilizer or root tab when growth slows, following the product instructions. Supplementary carbon dioxide is not essential, although a stable supply can improve growth and leaf development.

Growth and maintenance

Growth is usually slow. Remove damaged or melting leaves at the base and keep the filter intake from pulling on the plant. Newly planted Cryptocoryne may shed older leaves during adjustment, commonly called Cryptocoryne melt; leave the rooted plant in place and remove only decaying material.

Propagation

Propagation is normally by side shoots that develop from the rhizome or runners. Separate a young plant only after it has formed its own roots and several leaves. Replant it gently at the same depth, keeping the crown clear of the substrate.

Cryptocoryne parva (Dwarf Water Trumpet)

Medium

Foreground

Cryptocoryne parva is a small, slow-growing rosette plant suited to the foreground of freshwater aquariums. It forms narrow green leaves from a compact crown and remains one of the smallest commonly cultivated Cryptocoryne species. It is generally adaptable, but steady conditions and a nutrient-rich substrate help it establish. Like other Cryptocoryne, it may shed older leaves after planting or changes in water conditions before producing new submerged growth.
Gratiola viscidula (Sticky hedgehyssop)

Medium

Foreground

Gratiola viscidula is a small North American stem plant sold in the aquarium trade as Klebriges Gnadenkraut, or sticky hedgehyssop. Its narrow leaves form dense green shoots that can be maintained as a low foreground or short midground planting. The aquarium form is typically grown fully submerged, where regular trimming encourages branching and a compact appearance. Identification from trade photographs alone is not absolute, so the stated name should be retained when purchasing from a reputable source.
Taxiphyllum barbieri (Java moss)

Easy

On rock or root

Java moss is a hardy aquatic moss with finely branched, trailing shoots that attach readily to wood, rock and other surfaces. It tolerates low light and does not require a nutrient-rich substrate, making it suitable for beginners and low-tech aquariums. The supplied source identifies it as Taxiphyllum barbieri; visual appearance alone cannot reliably distinguish this moss from several similar aquarium mosses.
Rotala macrandra 'Japan' (Japanese loosestrife)

Advanced

Background

Rotala macrandra 'Japan' is a red-leaved aquarium stem plant sold under the common name Japanese loosestrife. It is generally regarded as a demanding form of Rotala macrandra and needs strong light, reliable carbon dioxide and consistent nutrition to maintain compact growth and good coloration. The supplied images support this identification, but cultivar names in aquarium commerce are not always standardized, so the exact form cannot be confirmed from images alone.
Pogostemon deccanensis (Indian star plant)

Advanced

Background

Pogostemon deccanensis is a bright green Asian stem plant with narrow leaves arranged in dense whorls around upright stems, creating a star-like appearance. It is best suited to planted aquariums with strong lighting, reliable carbon dioxide and regular fertilisation. Healthy growth depends on stable conditions, while trimming encourages branching and keeps dense groups from shading lower stems.
Hygrophila pinnatifida

Medium

On rock or root

Hygrophila pinnatifida is a distinctive Asian stem plant recognized by its deeply lobed leaves, contrasting veins and reddish stems. In aquariums it can grow as an upright plant or be trained across hardscape when side shoots are secured to rock or wood. Color and compactness vary with light, nutrients and carbon availability. The supplied image is consistent with this identification, although cultivar or regional form cannot be confirmed from an image alone.
Hygrophila lancea 'Araguaia'

Medium

Middleground

Hygrophila lancea 'Araguaia' is a narrow-leaved stem plant valued for its green to reddish-brown foliage and upright, branching growth. It is commonly sold under this name, although the identity and relationship of the aquarium form to formally described Hygrophila lancea should be treated cautiously. With strong light, adequate nutrients and carbon dioxide, it develops deeper coloration and compact growth. Regular trimming encourages side shoots and helps maintain a dense group in the middle or rear of an aquarium.
Hygrophila difformis (Water Wisteria)

Easy

Background

Hygrophila difformis is a fast-growing stem plant with distinctive deeply divided submerged leaves. It is commonly sold as water wisteria and is suitable for beginners when provided with adequate light and nutrients. Young tissue-culture plants may initially have emersed-form leaves, which can change substantially after submersion. Regular trimming helps maintain a compact group and encourages branching.
Hygrophila lancea 'Araguaia' (Araguaia Hygrophila)
