Some sort of Lilac?!

Not sure what this plant is, though the leaves, flowers, fragrance and habit remind me of Lilac so maybe it's an unusual variety. Regardless, it's one of my favourite plants! It's got a really rich scent that knocks you for six (in a good way!)

It's growing in the shade of a Corsican Pine, which provides real contrast- it's amazing how different plants can be from one another, and yet grow in each others' company with no trouble- a lesson humanity could learn from the plant world...?
