Shinnersia rivularis 'Weiß-Grün'

Shinnersia rivularis 'Weiß-Grün' is a cultivar of the Mexican oak leaf, a member of the daisy family that grows in Texas and northern Mexico in streams and rivers with a gentle current.¹ It was discovered in a nursery; it is characterised by white, yellowish to reddish leaf veins.¹²³ According to the specialist book, the cultivar is virus-infected; in emersed culture the virus can pass to other plants such as Hygrophila and Anubias and cause serious damage there.¹

With a height of 30–60 cm and shoots up to 10 cm wide, it is a background plant; as it grows quickly, it soon reaches the water surface.²³ Its colours develop best under good lighting, while high water temperatures suit it less well.³ Detached shoots can be planted as cuttings without further preparation.²³
