How to keep Hymenachne Amplexicaulis.
Light
The West Indian marsh grass springs from habitats with plenty of sunlight, like the shallow peripheries of ponds and lakes. It thrives best in full sun, but it can also cope with partial sun.
Temperature
West Indian marsh grass comes from tropical areas, which are generally hot and damp. Therefore, it is well-suited to thriving in conditions of high heat and moisture. It does not fare well with abrupt changes in temperature and favors a consistent temperature setting, making it vital to prevent temperature inconsistencies indoors. It typically cannot withstand cold temperatures and needs warmer conditions for its development. A substantial dip in the surrounding temperature could potentially halt its growth or even cause death.
