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.
