Who is the Blue Hygro?
This plant is quite rare and unknown in aquarium hobby. However, it can form a magnificent curtain of plants in the background of our tanks.
Needless to say that this Hygrophile is to be reserved for large aquariums or open aquariums. Moreover, this plant has a tendency to absolutely want to get its head out of the water quickly because it lives in its natural environment. Therefore, it can also be used in paludariums.
Under good conditions, this plant can flower in autumn. Its flower is red/purple.
Planting and maintenance
Planting and maintenance
How to plant and maintain the Blue Hygro?
For its foliage to be dense, it needs a very high luminosity. Please make sure that the light also reaches the base of the plant, otherwise the lowest leaves will fall off and leave the stem bald. To do this, cut the plant as soon as it reaches 30/40 cm (12 to 16"). This also prevents the plant from pulling its head out of the water, where its leaves can be burned if the light is not adequate.
We recommend adding fertiliser to prevent the leaves from turning yellow.
Apart from these points, it is an easy plant that does not pose any particular difficulties. It can be maintained by beginner aquarists.

Its name "Willow Leaf Hygrophiliac" comes from the shape of its leaves, which are reminiscent of those of the weeping willow.
Beware, most of the plants sold come from an emergent crop. As a result, the passage in immersed situation can be long and delicate and produces many failures.
Hygrophila salicifolia is sometimes synonymous with Hygrophila angustifolia. It can then be found under the name Hygrophila salicifolia var. angustifolia.
