Limnophila hippuridoides (commonly mistaken as Limnophila aromatica or Pogostemon stellatus). 4 large stems.

Nice stem plant from Asia. Long green leaves with bright pink undersides that get brighter with more light. The tops of the leaves can also turn white/pink under high light. Grows quite large with thick stems once well established (1.5-2" leaves). Seems to do better in hard, neutral water but can adapt to most conditions. Does not require high light or CO2.
