Hemigraphis Colorata 'Exotica' - Purple Dock leaf, Purple waffle
 
Hemigraphis Colorata has a rather interesting colour scheme, the typical green on most leaved plants like this one is diluted and greying out, while on the underside and some of the front face of the leaf is overtaken by a light purple. 
Deep purple foliage with a shimmering touch of silver creates an incredible contrast planted among plants with green foliage. 
The plant can be reproduced with cutting and replanting of the upper stems.
It can sucesfully being used in high humidity environment vivarium, terrariums or paludariums due to easy emersed growing nature.
In aquarium using root fertilisers and CO2 injection can be beneficial to improve growth and colour.
