Anthurium Magnificum Large

Athurium Magnificum is a rare plant native to rainforests in Central and South America, from Panama to Peru. It is an epiphytic perennial, characterised by large, leaves with prominent white veining. The Magnificum is not velvety like the Crystallinum, but it's leaves are more leather-like. It's petioles are four-sided or C-shaped.
 
Anthuriums fall under the Araceae family, a diverse genera (125 and over 3k species.)
 
Water & Humidity;
Water when topsoil is dry, do not keep it too moist when kept indoors. They thrive in humid conditions.
 
When ready to water make sure to water thoroughly and all around. I like to bring my plants to the sink for a good soak and then I let it drain completely. I usually place it on a saucer and empty it several times until there is no water coming out of the pot or left on the saucer.
 
 
Light
They prefer bright indirect light. 
 
Potting Medium & Fertilizer;
Like many epiphytic aroids, they need a well-draining mix; perlite, coco coir, orchid bark will do the trick. You can grow in sphagnum moss but will need to incorporate nutrients.
They benefit from fertilizer throughout spring and summer because they aren't super fast growers. Use a slow-release fertilizer and/or houseplant fertilizer and make sure to follow the packaging instructions (less is more.) I recommend new plant parents begin with slow-release fertilizers because they are more forgiving than liquid fertilizers. If you don't measure liquid fertilizers properly you could easily end up with leaf or root burn.
