About Lilyturf-like Primulina

Primulina ophiopogoides · also called Lilyturf-like Primulina, Mondo Grass Primulina · houseplant

Primulina ophiopogoides is a distinctive gesneriad from the limestone karst regions of Guangxi, China, named for its unusually narrow, grass-like leaves that resemble those of lilyturf (Ophiopogon). It is adapted to shaded, humid rocky shelves and performs best under dappled or filtered light with consistently moderate moisture. Overwatering is the leading cause of failure; water carefully and ensure the compost never becomes saturated. Not listed by the ASPCA; treat as mildly toxic and keep away from pets.

Preferred mix: Free-draining gesneriad or African violet mix amended with extra perlite

Watch for — Root rot from overwatering: The narrow root system is particularly vulnerable to anaerobic conditions; if leaves yellow and collapse despite adequate watering, unpot and inspect roots — trim any brown, mushy roots and repot into dry, fresh gritty mix.
