Pogostemon deccanensis (Indian star plant)

12 October 2026

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.

Pogostemon deccanensis (Indian star plant)

Identification

This plant forms upright, relatively slender stems with many narrow, pointed leaves in whorls. The dense leaf clusters give each stem a star-like outline. The supplied source identifies it as Pogostemon deccanensis; cultivated plants can resemble other narrow-leaved Pogostemon species, so identification from appearance alone should be treated as provisional.

Placement and planting

Use it in a group as a background or tall middleground accent. Separate individual stems before planting and insert them into the substrate with space between them. Avoid burying the leaves or packing the stems tightly, because restricted circulation and shade can lead to deterioration near the base.

Light and carbon

Strong aquarium lighting helps maintain compact growth and dense, bright foliage. A consistent carbon-dioxide supply is highly beneficial and is generally needed for dependable long-term performance. Under weaker light or without added carbon, stems may become more open and growth may be less vigorous.

Fertilisation and water quality

Provide a complete fertiliser programme with adequate macronutrients and trace elements. Keep conditions stable and remove decaying leaves promptly. Good circulation helps distribute carbon and nutrients through a dense planting, while regular maintenance prevents neighbouring plants from shading the lower portions.

Trimming and propagation

Propagate by cutting healthy stem tips or side shoots and replanting them. Trim above a healthy leaf node to encourage new shoots from the remaining stem. Replant vigorous tops to renew the group, and remove old lower sections if they have become bare or weakened.

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.

Middleground

Hygrophila lancea 'Araguaia' is a compact, narrow-leaved stem plant valued for its red to pink coloration and branching growth. It is commonly sold under the aquarium trade name “Araguaia,” but the exact origin and taxonomic status of this cultivated form are not fully certain from the supplied material. With strong light, a nutrient-rich substrate, and reliable carbon availability, it can form a dense midground group. Regular trimming encourages bushier growth and provides cuttings for propagation.
Hottonia palustris (Water Violet)

Easy

Background

Hottonia palustris is a delicate European stem plant with finely divided, feather-like leaves arranged along upright shoots. It is sold by Tropica as a 1-2-GROW! InVitro plant and is suitable for the background or middle of a planted aquarium. The supplied label supports the identification, although aquarium-grown specimens can vary in leaf form during transition from emersed to submerged growth.
Cryptocoryne nurii (Heart-leaf Water Trumpet)

Medium

Foreground

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.
Helanthium tenellum 'Green' (Green Dwarf Chain Sword)

Easy

Foreground

Helanthium tenellum 'Green' is a small, grass-like rosette plant used mainly in the foreground of freshwater aquariums. It spreads through slender runners and can form a low, connected carpet when planted in suitable substrate. The supplied source identifies it as the green cultivar, although cultivation conditions can make its leaf width and height variable. It is generally adaptable, but stronger light, adequate nutrients and added carbon support denser growth.
Najas guadalupensis 'Guppy Grass' (Guppy Grass)

Easy

Supporting plants

Guppy Grass is a fast-growing, delicate submerged stem plant identified here as Najas guadalupensis 'Guppy Grass'. It produces narrow, flexible green leaves along branching stems and forms dense cover for small fish and fry. It is generally undemanding, grows floating or planted, and can quickly fill open water. The exact horticultural distinction of the quoted form cannot be confirmed from the supplied material alone.
