Here in the States, this flower is commonly known as Hibiscus. Where I grew up, we call it Gumamela. It is considered wild in the Philippines. Back then we would squeeze the juice out from the flower and mix it with a sliver of laundry soap. The concoction made great bubbles, which could be as large as our heads. Of course, we were only 7 years old then-- so they probably were not that big. Hope your day is going well.
