Dennerle - Hygrophila corymbosa 'Thailand'

Dennerle - Hygrophila corymbosa 'Thailand' Hygrophila corymbosa 'Thailand' is a narrow-leaved form of H. corymbosa that produces elegant upright stems and long, slender foliage. Under normal lighting the leaves remain fresh green, while stronger light can bring out warmer reddish-brown tones. Its rapid growth makes it useful for quickly adding height and plant mass to a new aquarium. It performs best with regular fertilisation and good lighting, and routine trimming can be used to control height and encourage a fuller, branching background group.

Unlike traditional rockwool-grown aquarium plants, the plug does not need to be removed before planting. Simply remove the plant from the outer packaging, rinse gently if needed, and plant the coconut plug directly into the substrate. The roots can continue growing through the plug and into the surrounding substrate. Please note: As this is a living plant, size, leaf shape, colour, and fullness may vary slightly from the product images and between individual specimens. Some emersed-grown leaves may change as the plant adapts to submerged aquarium growth.
