I just bought this plant today. I have admired it many times when I have seen it in the past. From what I have read today, Prayer plant is very easy to grow. It is a good beginner plant. It is also called Maranta.
Prayer plant likes bright light, but not direct sunlight. It is a fast grower according to the sources I have read, and is flexible with soil- just doesn’t like to be soggy- most plants like well-drained soil.
I have read some places that they like to be misted with water on leaves and that they prefer a higher humidity. I usually wait to see how a plant does before I spend the time to do any extra things above and beyond watering. I like to try to keep things simple and low-maintenance with my plants. So, if it starts to die, maybe I will look at misting or getting a humidity tray for the plant to set on.
Will post some updates after I have had this plant for a while (2-10-12).
I think the soil I purchased might not be draining well- I might have to repot. (4-14-12)
