Matthiola incana 'Pillow Talk' has the most heavily scented flowers and just a few stems can fill a room with a lovely fragrance. 

This plant has long been a cottage garden favourite, grown in the border for its masses of white flowers, or for the vase. It can also be grown in a container and is perfect for the patio, where the scent can be enjoyed while enjoying a well-earned break from the gardening.
