this plant needs so much more water than i thought. I used to keep it in a glass pot but it does not work out.
It was drying out because i cannot give a lot of water into a glass pot(without drainage).
I finally placed it into a ceramic pot with a hole at the bottom and watered it thoroughly.
It grows nicely again now. I am so happy.
how about growing this plant in very big area? It will be really nice to look at!
