Blue flowers are really uncommon and what is interesting about this climber is that the there are 2 sets of petals, one shorter and darker than the other set of longer but paler petals. The interesting element of this plant does not stop here.
When the flowers dry up, they turn brown, hence the common name. When the dried brown flowers are shed or when you pluck them and throw them into the air, the dried flowers would spiral and spin all the way with its descent to the ground. Can you imagine the sight of having a palmful of it and releasing them from a higher ground? I can and it's beautiful.
