DSC_0914 (3)gil•ly•flow•er \ GHIL ee FLAU er \ n : an Old World pink that is grown for its clove-scented flowers and is the source of garden carnations [by folk etymology from Middle English gilofre “clove”] (Webster’s New Encyclopedic Dictionary)

In the Middle Ages, the gillyflower (Dianthus caryophyllus) was combined with cinnamon in cooking sauces or used to flavour wine and ale and was a common additive to potpourri. Because it could be grown indoors year-round in windowsill pots, it was often used to pay rents.
