Description

'Starbright' mockorange was developed at the Memorial University Botanical Garden in Newfoundland. Bronzy-purple new growth is followed by exceptionally large flowers accented by a purplish-black calyx. As it opens, it looks like a little star. It is hardier than most other varieties, and is sterile.
