Name: Hygrophila corymbosa|
Origin: India, Malaysia, Indonesia|
This is a beautiful and hardy plant that doesn't require much attention to grow well. It grows pretty large leaves, allowing a single stem to occupy a significant part of the tank. Left alone, it easily crosses the water surface and begins to assume its emersed form: the leaves are darker and harder, and the plant produces purple flowers that give out a pleasant scent. But in this case it also ends up shedding all underwater leaves, so frequent pruning is required if you don't want that. Any pruned stem may be buried in the gravel and will readily generate a new plant. Even without enriched soil, this plant will create strong roots. There seems to be some confusion in literature between the names Hygrophila corymbosa, Hygrophila stricta and Nomaphila stricta. Possibly these are all variants of the same species.
I have found giant hygro to retain more of its lower leaves if the gravel is fortified with iron and minerals, and if enough light reaches the bottom of the plant. This plant is great for sucking up ammonium and nitrates quickly, and can be a real asset in the war against algae. One characteristic of this plant is the brown stems. I also keep mine pruned to encourage branching and to create a dense, bushy plant.
This plant will grow quick and big. I pruned mine and thought I may have overdone it and in about a week it was almost as full as it was before. Great plant in my opinion!
An excellent plant. I keep mine in plain sand, with no added nutrients and it grows to the point of being out of control. And a great plant for the back of your tank.
I have this beautiful plant in a 90 liter, with no added nutrients and no CO2 injector and its growing like mad. I also only have a 20 Watt tube. It's a great looking plant that is perfect for the back of the tank. My fish love swimming through the leaves.
I bought two of this beautiful plant. I put one in the centre, in the brightest part of the tank, and the other in a rather dark corner. The one in the bright spot was sprouting all over the place and takes up the majority of the back of the tank, but the other's leaves began to die under the low light, and the stems broke. It started sprouting on the broken stems, but unfortunately they died and my clown loaches finished off the rest of it. Great plant when in bright light, But a real tank buster if not pruned at least once a week!
