'Good hedging plant' does not do this fine shrub justice (although it is indeed excellent as a hedge!). We grow it as a specimen just off the South Walk and its rich and sugary scent wafts great distances over the Systematic Beds.
The simply elegant and entire, bluish narrowly ovate leaves set off the pure white flowers perfectly. Four narrow petals with rounded tips are clearly fused and advertise the parrot's beak of two yellow and orange stamens at the centre.
It belongs rather improbably to the olive, Oleaceae, family.
