Hygrophila sp. 'Bold'

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Ideal as a strong focal point in the midground or background where its bold colors can stand out. Planting it adjacent to light green, finely textured plants creates a stunning visual contrast. It requires an unobstructed location to receive the intense light it needs for coloration.

Botanical form

Stem

Features moderately sized leaves that can develop intense reddish, purplish, or bronze coloration under optimal conditions. The stems are relatively sturdy and grow upright. The coloration is usually most intense near the top of the plant closest to the light.

Growth

very-fast

Has a moderate to fast growth rate, especially when provided with CO2 and high light. Its growth is somewhat more manageable than the fastest Hygrophila species, allowing for easier aquascaping. Regular trimming helps maintain a neat, bushy appearance.

Substrate

Low

Hygrophila sp. 'Bold' is a relatively undemanding plant that easily adapts to low-nutrient substrates such as standard aquarium gravel or sand. It develops a widespread root structure primarily focused on securing its stems to the bottom, requiring a substrate depth of 3 to 5 cm. Since it draws most of its required nutrients directly from the water column, a nutrient-rich substrate is beneficial but not strictly required.

Column fertilization

Recommended

Relies significantly on water column fertilization to maintain its vibrant hues. A comprehensive liquid fertilizer with extra iron is crucial for best results. It will quickly show signs of deficiency, such as pale leaves, if nutrients are lacking.

Root fertilization

None

Benefits from a nutrient-rich substrate, which helps support strong root development and overall plant health. Root tabs can provide a good backup source of nutrients. However, water column feeding is generally more important for achieving intense leaf color.

Trimming

Occasional

Responds excellently to trimming, which is necessary to encourage lateral branching and a denser form. Trimming the tops off will force the plant to become bushier, creating a solid block of color. The colorful cuttings are easily replanted to expand the group.

Propagation

Cuttings

Easily propagated by taking stem cuttings and replanting them in the substrate. The cuttings usually root quickly and begin growing within a few days. It is a rewarding plant to propagate due to its beautiful coloration.

Sensitivity

Moderate

Somewhat more demanding than plain green Hygrophila species, requiring good light and nutrients to look its best. It can lose its vibrant coloration and become leggy if light or nutrients are insufficient. However, it is still relatively hardy once established.

Layout role

Midground, Background

Functions perfectly as a striking color accent to break up the monotonous green of a typical aquascape. Its deep reddish hues provide dramatic contrast and draw the eye. It is excellent for creating a vibrant, structural midground bush.
