The family of Scrophulariaceae includes about 2000 species of plants, herbaceous perennials and annuali.A this family belong to many aquatic plants and marsh plants such as those commercially available aquarium kinds of Bacopa, Hydrotriche, Limnophila , Micranthemum, Hemianthus. The kind
Hemianthus was established in 1817 by botanist Nuttall and means "half flower" The flower, in fact, has a corolla with a very noticeable compared to only lip flower Micranthemum instead it has two.
Hemianthus callitrichoides "Cuba", one of the smallest known aquatic plants and is considered by some recent studies a form of local Micranthemum umbrosum . Its name means like Callitriche , a kind of submerged aquatic plants (often emerge from the tips, forming thickets) present in stagnant water or low flow even in Italy.
native of Cuba, was discovered for the aquarium by Tropica's founder Holger Windeløv during the dry season in a river near Las Pozas, about 90 km east of Havana.
marsh plant cultivation has hard leaves of a few mm in length placed on several long creeping stems cm.Grazie a questo portamento la pianta riesce a formare un fitto tappeto dal colore verde chiaro,rifiugo per molti microrganismi.La sua crescita è favorita da una temperatura compresa tra i 20-26°,un fondo soffice e ben fertilizzato(meglio se maturo),intensa illuminazione e costante apporto di CO2.Talvolta cresce anche come epifita assimilando le sostanze nutritive esclusivamente dalla colonna d'acqua che dovrà essere ricca di nutrienti.
Il modo migliore per collocare e far attecchire la pianta consiste nel dividere il pane di grodan in diversi tocchetti che andranno poi immersi nel substrato a distanza di qualche cm.Un altro metodo, più invasivo,prevede l'elimininazione completa del grodan dalle radici e la messa a dimora di piccoli ciuffi o selected individual stems.
Pruning should be carried out regularly (to avoid any unnecessary inconvenience)-style "lawn" with the help of special scissors curved blade.
