Here's a great article from Tropica about this plant written by our friend and brilliant aquascaper George Farmer: https://tropica.com/en/articles/lagenandra-meeboldii-red/

This plant is originally from India and is quite similar to a medium-sized, broad-leaved Cryptocoryne. It can be used in the aquarium like Cryptocorynes, but needs sufficient light to develop colours.

The leaves are 4-8 cm wide and 6-12 cm long, so the whole plant becomes relatively wide.
The colours range from dusty green with bright violet to red-violet often on the same leaf. New leaves are pale pink.

Pots are brimming with plants and have lots of mass and healthy,
well-developed roots.
Most pots can be divided into several portions or individual plants which are planted separately.
