Jasmine

Jasmine looking well just presently. Apparently a species that might flower any time between now and next April.

RHS and Wikipedia agree that the jasmine - this one probably being jasminum nudiflorum - is a member of the olive family. But the RHS talks of this one coming from China, while Wikipedia talks of the centre of diversity being south east Asia. The plant for which (nearly) all the tea in China is named.
