Plant of the Day Hygrophila 'Siamensis 53B'

Posted by Ruth McDonald on

We couldn't start plant of the day without looking at 53b. It started last year when Tom Ackrill and George Farmer were talking about plants suitable to replace a large Amazon Sword. George suggested 53B. Soon everyone seemed to want to get their hands on this plant, and today it is still our best selling plant in the shop. 

But what is it? 

Hygrophila corymbosa 'Siamensis 53B' is a variety of Hygrophila corymbosa 'Siamensis'Hygrophila plants have the unappealing name of swampweeds, but there are many of our aquarium favourites hiding in the genus, from Water Wisteria through to Hygrophila polysperma originally known as oriental ludwigia. There is up to 100 species in the genus, and not all are fully aquatic. 

 Why is Hygrophila 'Siamensis 53B' so attractive to us aquarists? Give a decent substrate, some fertilisers and good light is will grow rapidly, forming an incredible amount of side shoots and becomes bushy relatively rapidly.

Stems becomes 15-40 cm tall and 7-12 cm wide. Its beautiful bright green leaves are narrower than the regular 'Siamensis' and it can achieve red-brown leaves in good light conditions. An undemanding, fast growing plant that requires frequent pruning to maintain a bushy growth.

 Even better you can replant cut-off shoots; they will soon form new roots and grow. Giving you an almost endless supply of these great background plants. 

Did you know that if you allow Hygrophila corymbosa to emerge from the water it will flower? With purple flowers this plant is one to consider for open topped tanks where you want things happening above the water as well.
