Under simple aquarium conditions, Lysimachia parvifolia ‘Red’ already develops a reddish coloration. With improved lighting and good nutrient availability, the leaves become increasingly intense in colour, making it an attractive accent plant in the midground or background.

The submerged leaves are small, rounded and resemble baby spinach, which is why the plant is sometimes referred to as Samolus parviflorus ‘Red’. The true Samolus parviflorus is a green aquarium plant with a very similar leaf shape, but Lysimachia parvifolia stands out due to its red hues.

Growth is upright and compact when regularly trimmed, and the plant responds well to replanting of cut shoots. Stable conditions and a balanced nutrient supply ensure the best colour development.

Outside the aquarium hobby, Lysimachia parvifolia has been used in Traditional Chinese Medicine as an anti-inflammatory herb.
