Try Leucothoe axillaris, because that's what it is. Stachyurus is a
genus of deciduous shrubs/small trees, which discounts it in the first
place. Give the plant another few weeks for the flowers to develop
fully because the photograph portrays one that has a little way to go
yet. As the inflorescence develops, the basal bracts dehisce and are
not normally present by the time the flowers have reached maturity.
