Among aquarium favorites, there are inconspicuous ones, and there are real stars. Hygrophila limonita belongs to the latter. It instantly attracts attention with its unusual beauty, which seems to have been created according to special mathematical rules.
Its main decoration is its leaves. They are arranged on the stem in perfect pairs, one opposite the other, creating a strict, symmetrical pattern. And the color is like something out of a fantasy world: silvery-olive, sometimes with a slight pinkish tint. This “silvering” gives the plant a delicate and noble appearance.
In the aquarium substrate, Hygrophila lemmonii creates spectacular, dense bushes. It does not just grow, but forms a living sculpture with clear geometry. With good lighting, it appears in all its glory, becoming the central element of the underwater landscape.
Despite its aristocratic appearance, this plant is quite easy to care for. It is suitable even for beginners who want to add a little perfect natural harmony and unearthly glow to their aquarium.
Distribution
Its main habitat is the water bodies of Southeast Asia. The plant is often found in marshy areas, thanks to which it thrives in paludariums or humid greenhouses.


Growing and care
Hygrophila corymbosa is widely used in aquarium design due to its decorative appearance. It looks great in the background or center of a composition. Lemongrass grows year-round in both height and width, sprouting additional side shoots.
The plant is best kept in a tropical aquarium. It is recommended to use large-volume vessels where Hygrophila corymbosa can grow upwards undisturbed and form a lush bush if necessary. Experienced Hygrophila owners advise cutting it back to 25 cm in height.
Water parameters for ideal maintenance
Hygrophila corymbosa grows best in moderately hard water with a slightly alkaline or neutral pH. It reacts quite sharply to changes in water conditions, shedding its leaves and losing strength.
To keep lemongrass in good condition, it is recommended to maintain the following water parameters in the aquarium:
- acid-alkaline balance — 5.5-8.


The plant must be kept in clean water. Replace 1/5 or ¼ of the total volume of water every week.
Lighting requirements
Hygrophila corymbosa is a typical tropical plant that needs a lot of light.
Ideally, the light intensity should be at least 50 lm/l. The recommended duration of daylight hours is 12 hours.
Insufficient lighting weakens the plant. Hygrophila begins to shed its lower leaves and fade. If the light flow is set correctly, the plant will not only have healthy green leaves, but also a bright brown stem.
Experienced aquarists prefer to use it when setting up light sources.
Requirements for soil and nutrient substrate
Hygrophila corymbosa has a well-developed root system. For proper rhizome formation, it is recommended to plant the plant in soil 5-7 cm thick. A nutritious substrate containing clay, which is a source of iron for aquatic plants, is preferable.
If the aquarium contains mainly solitary plants with strong, powerful roots, they can be planted in “empty” soil such as sand or small pebbles, after placing tableted fertilizers under the roots. Experienced owners of aquatic plants consider this an economical way to green an aquarium.
When choosing nutritious soils, pay attention to:
Fertilizer requirements
For Hygrophila corymbosa, mineral fertilization is not essential. At the same time, it will be useful to have silt, which usually accumulates in old aquariums.
Do not add table salt or baking soda to an aquarium with lemongrass. Increased sodium concentration has a detrimental effect on the plant.
Despite the unpretentiousness of the shield-shaped hygrophila, it is desirable to provide it with microelements for healthy growth. In particular, iron, thanks to which the leaves of lemongrass retain their rich green color.


The plant receives almost all of its nutrition through its powerful roots, so it is best to use tableted fertilizers such as:
Hygrophila lemongrass is an aquarium plant that stands out not only for its beauty, but also for something special: its leaves grow strictly in pairs, creating a symmetrical pattern, as if someone had carefully arranged them with a ruler. The leaves are slightly silvery, as if dusted, and in good light they give off a slight glow. It grows quickly, but remains neat, as if it knows where it needs to grow. It is like a living decoration for an aquarium — natural, but with a touch of order and style.
Reproduction
When grown in an aquarium, Hygrophila corymbosa is propagated by cuttings. To do this, side branches or part of the main stem are separated from the mother plant. The recommended length of the cutting is 8-10 cm. The cut part is buried in the soil, where it will eventually take root.
Variations and forms of the plant
In addition to lemongrass, there are many types of hygrophilous plants grown in aquariums. Let's look at some popular examples:

- Willow-leaved. Like lemongrass, it grows in Southeast Asia in swampy areas and water bodies. It grows to an average height of 30-40 cm and has long, narrow leaves up to 12 cm long. The edges of the leaf plates are smooth or slightly serrated.

- It is a multi-seeded plant. The light green oval leaves of this hygrophila are located on a long, strong stem. The leaf plates can be rounded or slightly pointed. The leaves usually have pinkish veins.

- Pinnatifida. Grows up to 15-30 cm in height. Depending on the lighting, the plant can range in color from red-burgundy to bright green. It can grow on rocks and driftwood and has a weak root system.

- Araguaia. Grows in Japan, Hong Kong, and Brazil. The plant grows up to 15 cm in height. In its underwater form, it has narrow reddish-brown leaves with a longitudinal silver stripe.

- Compact shield-shaped. Similar in appearance to lemongrass, but smaller in size, as reflected in the species name. This hygrophila has a bushy appearance due to its large number of side shoots. It grows very slowly.
Hygrophila citrifolia is a plant that can safely be called the decoration of any aquarium. Its slender stems and neat, symmetrical leaves give the underwater landscape a special structure and order.
But the beauty of this plant is not just an external effect. It is also quite unpretentious, which makes it an excellent choice for both experienced aquarists and beginners. With good lighting and sufficient nutrients, it will grow quickly and delight you with its silvery-green glow.
Plant Hygrophila citrifolia in the middle or background of your aquarium. You will see how it enlivens the entire composition, adding volume, light, and that very geometry for which it is so valued by lovers of underwater gardens.
