Q.A Jasmine type shrub
I have a jasmine type shrub with star shaped white flowers which, in qld flowers several times per year. It has quite thick stems and large glossy green leaves. When the stems are broken they release a milky sap. When they have finished flowering, it has large red fruit which are red and fleshy inside. My question is, can you tell me the name of the plan, a little about it including how to propagate and are the fruit edible. Thanks.

This is called Boxwood Beauty.
