One of my favourite things about summer is the smell of gardenias. When I was a little girl, I planted a gardenia tree outside my bedroom window so I could smell the perfume when the window was open on warm summer nights.
I now have a gardenia hedge which, despite being neglected this year, has nevertheless produced beautiful blooms. This would be thanks to the weeks of wet weather, most likely.
I keep a bunch on my desk so I have the fragrance with me all day and park my car near the hedge so I can smell the flowers every time I go out!
