Orange is the prominent colour in my garden for the week when my orange Hibiscus rosa-sinensis sends out a flower or two on different days. The colour is more dominant when the vine, Chinese hat plant (Holmskioldia sanguinea) next to it is blooming at the same time.
In the late afternoon or when the sky is cloudy, the little hat-shaped blooms are still very obvious. Perhaps that is why the yellow-bellied sunbirds like to visit and often perch on the vine.
