Anthuriums are an aroid and an epiphyte, originating from Central America.
Being an epiphyte (attaches to other plants) we highly recommend a very well draining mix including orchid bark & Fern Fibre.
Water through thoroughly & then allow do mostly dry out before watering again.
The sphagnum moss around the top of the pot is to recommended to provide the higher level of humidity this plant prefers. Keep the moss wet as much as possible too help it thrive!
Place in bright indirect light, but dont allow to sit in harsh light or its leaves may burn.
This is a maturing seedling.
