I have had a Sarcococca humilis in the garden for six years.
Every year, it is loaded with buds and every year, the buds abort before they open.
Is it like camellias, wherein, if too short of water in late summer, when they are forming their buds, they abort just as they are about to open?
It is in the shade of an apricot tree, where everything else, seems very happy.
