Papaver somniferum, commonly known as the opium poppy, or breadseed poppy. It is the species of plant from which opium and poppy seeds are derived and is a valuable ornamental plant, grown in gardens.Poppy seeds are used as a food in many cultures. They may be used whole by bakers to decorate their products or milled and mixed with sugar as a sweet filling. They have a creamy and nut-like flavor, and when used with ground coconut, the seeds provide a unique and flavour-rich curry base. They can be dry roasted and ground to be used in wet curry (curry paste) or dry curry.
