This vine plant flowers throughout the whole year. According to a book entitled Tropical Plants, the genus of this rainforest flower is thunbergia. The species name is Thunbergia grandiflora Roxb. Its English name is Sky Vine or Blue Trumpet Vine. We can easily see them in open areas of the rainforest that receives full sunshine. The pale blue colors of these rainforest flowers look contrast in the middle of the dark green leaves of the plants and their supporting trees. The petals of the blue trumpet vine are soft. I photographed them when I was hiking in the Table Mountain of Manokwari. City dwellers in Manokwari have not considered the vine as a commercial decorative plant. So, it's relatively easy to find them at certain empty land areas in the city where bush plants and vines still grow.
