Comment:

While jogging after dinner near my neighborhood, I saw many honey bees (Apis mellifera) still foraging on this plant around 8 pm, so I took a small sample home to do UV photographing. Flowers are very fragrant. The red/pinkish stripes are more UV absorptive under UV. Tip of petals are bluish under UV but the lower part of the fused petals are UV bright (nearly white) with stripes.
