Asiatic mangrove (Rhizophora mucronata)

Product description

This Asiatic mangrove species has the largest propagules of all mangroves. They are on average 40-50 cm long, but can sometimes reach a length of up to 1 metre. Propagules are the structures that form after the seeds germinate on the tree: a process that all Rhizophora species undergo. When fully grown, they fall from the tree and either stick directly into the mud or float like a bobber for further dispersal.

This mangrove species occurs along all tropical coasts of the Indian Ocean. In tidal areas directly along the coast, but also further inland in river deltas where the water can be fresh. The many characteristic aerial roots provide sufficient oxygen and have an important function in coastal protection. It is a slow grower that can eventually reach a height of 20 metres in the tropics. We can keep this species as a houseplant in a large vase with water, but also in an aquarium or paludarium, for example. The optimum growing temperature is between 20 and 28 degrees Celsius and the species likes a light/sunny location. A sandy or muddy mixture can be used as substrate. Initially, a layer of 10 cm would be sufficient, but later the roots will need more space. The water level can vary from just above the substrate to the leaves.
  
Sowing description: Insert the seed with the thicker bottom into the substrate. A temperature of 25-28 °C is optimal for initial development.
