Sweet Williams or Dianthus Barbatus are traditional English Garden plants. They have clusters of deliciously clove scented flowers with notched petals and quite broad leaves with entertaining whiskery tufts poking through the flowers.
They are excellent as cut flowers so grow some for show in your borders or containers and some just for cutting! They will last for a least a week in a vase but do not place in a sunny spot. Sweet William flowers can also be dried and used for pot pourri.
They come in all shades of lilac, pink, white and red; there are single or double varieties; a selection of markings and eyes and in a range of heights from 6 inches to 2 foot (15 to 60 cms) so it is easy to find one that is suitable for your garden
They are very easy to grow and flower from late spring through to summer and are much loved by butterflies and bees.
Sweet Williams are biennials which means that the seed is sown one year and then they flower the next year. In milder climates they can survive the winter - in USA -zones 4-10.
