From the Family Verbenaceae and commonly known as Golden Dewdrop, Skyflower, this beautiful plant has several species and cultivars and I do not know the real identity. This and its other species and cultivars are often pruned as a low hedge here, which to me kind of diminishes the value of the plant. Whilst I agree that it can make a pretty yellow hedge, it is best planted as a specimen plant so that it can grow, flower and fruit freely. And I look forward to the day when I see this old plant flourish in our landscape, by expressing the biodiversity value it truly brings to our environment.
