Honestly, when I first saw this plant I thought that it is a Pitcher plant or something similar. I'm not familiar with this plant and so I took some leaf samples and check online about it.
It turns out that this is a Hawaiian Air plant. They are not ornamental however many seem to like this plant that they brought it home and grow them. It's very simple to grow. You just have to take a while leaf and place them in a damped cloth or in between the pages of a book. Keep them there for a week or two weeks and come back to see if the roots and tiny leaves grow on its edges. If there are then it can already be replanted on a pot with soil.
The bell-like features dangling on its stems are the flowers.
