I like blue flowers:) They draw me into the realm of a calm blue ocean. And Bunga Telang flowers are the 'blue-est' I can get on this tropical island.
Here's the flowers in single-petalled form,
and double-petal form.
The plants grows easily, with little maintenance. Let them indulge in abundance of sunshine, and they'll be bloom their heads away. That delighted Kimi-the-cat. She has taken to eating the blue flowers (one big chomp) and leaves!
