This is probably one of the most popular wild flowers in Europe, both for its beauty, and its WorldWar I memorial. The plant is an annual herb which readily germinates from seeds. The branching stems have fine white or purple-red hair all along, especially at the flowering part. The flower stems are quite slender, and holds the solitary and terminal flowers. The bud is hanged upside down and then assumes a normal position just before blossoming. The stems have a white milky sap.

Most of the leaves are more or less found at the middle or lower part of the stem, leaving the flowers more conspicuous. They are stalked, oppositely arranged on the stems, and are so deeply pinnately divided, that each pinna (leaf lobe) is independent. They also have a coarsely serrated outline. The leaf pinnae and serrated outline varies from plant to plant.

The flower consists of 2 hairy sepals and 4 bright red to red-crimson petals, often having a dark blob at the base. The blob also varies from plant to plant and some may even lack it. The petals are fragile (detaches easily from the flower) and their size vary considerably, but can form flowers of about 50mm in diameter. At the center there is a globular or pot-shaped gynoecium that is pale green in colour and has radiating darker stripes at the top. The stigma are found upon these stripes. Encircling the base of the gynoecium is a cluster of many black stamens with anthers that may be covered with pale yellow or grey pollen.

The fruit is a seed capsule which is pale green and turns yellowish or light brown when the seeds matures. The glabrous seed-capsule is pot-shaped with a flattened top (lid) that has a slightly serrated circumference. The dehiscent poricidal capsule is operculate (possess a lid structure). It does not split open, but instead, the tiny (1mm), brown, kidney shaped seeds escape from pores at the lid part of the capsule when wind causes it to sway.

Cultivation Notes:

Prefers a well-drained sandy loam in a sunny position [1, 200]. Does not do well on wet clay soils but succeeds in most other soils [115]. Plants usualy self-sow freely when growing in suitable conditions so long as the soil surface is disturbed [238]. There are several named varieties selected for their ornamental value [200]. A polymorphic species, varying in leaf shape and flower colour [17]. When growing in cereal fields, poppies decrease the yields of nearby cereal plants [18, 20]. Members of this genus are rarely if ever troubled by browsing deer or rabbits [233].

Constituents

Papaver Rhoeas is very slightly narcotic. The chief constituent of the fresh petals is the red colouring matter, which consists of Rhoeadic and Papaveric acids. This colour is much darkened by alkalis. [WWW-03]

All parts of the plant contain the crystalline non-poisonous alkaloid Rhoeadine. The amount of active ingredients is very small and rather uncertain in quantity. There is great controversy as to the presence of Morphine. Also it has not been determined whether Meconic Acid, which is present in opium, is a constituent. [WWW-03]

Medicinal Uses:

The plant has the following medicinal properties:   [4, 7, 9, 13, 46, 53].

Anodyne	used to relieve pain.    [WWW-32]
AntiCancer	used in the treatment of cancer; "anticancer drug"; "an antineoplastic effect".    [WWW-32]
Emmenagogue	used to promote the menstrual discharge.    [WWW-32]
Emollient	substances resembling cream that have a soothing and moisturising effect when applied to the skin.    [WWW-32]
Hypnotic	used to promote sleep where the effect is intermediate between that of a sedative (tranquilizer) and narcotic.    [271]
Sedative	used for making drowsy or sooth a patient, but not strong enough to induce sleep    [271]

The flowers of corn poppy have a long history of medicinal usage, especially for ailments in the elderly and children [244, 254]. Chiefly employed as a mild pain reliever and as a treatment for irritable coughs, it also helps to reduce nervous over-activity [254]. Unlike the related opium poppy (P. somniferum) it is non-addictive [244]. However, the plant does contain alkaloids, which are still under investigation, and so should only be used under the supervision of a qualified herbalist [244].

The flowers and petals are anodyne, emollient, emmenagogue, expectorant, hypnotic, slightly narcotic and sedative [4, 7, 9, 13, 46, 53]. An infusion is taken internally in the treatment of bronchial complaints and coughs, insomnia, poor digestion, nervous digestive disorders and minor painful conditions [9, 238]. The flowers are also used in the treatment of jaundice [218]. The petals are harvested as the flowers open and are dried for later use [238]. They should be collected on a dry day and can be dried or made into a syrup [4].

The latex in the seed-pods is narcotic and slightly sedative [240]. It can be used in very small quantities, and under expert supervision, as a sleep-inducing drug [7].

The leaves and seeds are tonic [240]. They are useful in the treatment of low fevers [240].

The plant has anticancer properties [218].

Artemis Herbs Ltd makes a Tincture of Field Poppy flower which gives the following info and uses:
This tincture is made from flowers gathered in Lebanon where the field poppy grows abundantly. It produces a beautiful bright red tincture which is an ideal remedy for nervous over-activity and insomnia. It has soothing, anti-catarrhal properties, good in irritable coughs, croup, bronchitis and pleurisy. Suitable for children. Do not exceed recommended dosage. [WWW-10]

Edible Uses:

Seeds - raw or cooked. Much used as a flavouring in cakes, bread, fruit salads etc. [4, 5, 21, 183], it imparts a very nice nutty flavour [KF]. The seeds are rather small, but they are contained in fairly large seed pods and so are easy to harvest. The seeds are perfectly safe to eat, containing none of the alkaloids associated with other parts of the plant [238]. An edible oil is obtained from the seeds [2, 4]. This is said to be an excellent substitute for olive oil [4, 183], it can be used in salad dressings or for cooking. [2]

Leaves - raw or cooked [7, 52]. Used like spinach or as a flavouring in soups and salads [132, 183]. The leaves should not be used after the flower buds have formed [7]. Some caution is advised, see the notes above on toxicity.

Flower - A syrup can be prepared from the scarlet flower petals, it is used in soups, gruels etc. [4, 183]. In the past it was also used as a substitute for tea. A red dye from the petals is used as a food flavouring, especially in wine [183].

Other Uses

A red dye is obtained from the flowers [7, 46, 61], though it is very fugitive [4]. A syrup made from the petals has been used as a colouring matter for old inks [4, 13, 89]. The red petals are used to add colour to pot-pourri [238].

Misc:

• Origin of the Poppy is probably Asia and Far East. [277]
  
• Flour made from corn that is badly cleaned from poppy (esp if high content of poppy seeds is present) will have a yellowish colour and deteriorates quickly.[277]
  
• Because of improved methods of cleaning grains and crops from weeds, the field poppy is slowly disappearing from the fields, despite that one plant can produce 50,000 seeds. [277]
  
• There are several varieties, differing in the size of the lobes of the leaves and in the character of the fruit, which may be nearly cylindrical or globular, smooth or furnished with stiff hairs. The intensity of the scarlet colouring of the petals also varies [WWW-03]
• The poppy was established as a memorial flower of the First World War by a Georgia woman named Moina Michael, and was accepted by the American Legion as its official memorial flower in 1921. It has been used by the American Legion and similar organizations around the world in honor and remembrance of veterans and active miltary service personnel from every war up to the present. [AJ]

Personal Observations:

There seems to be genetical variety in the blobs present in the base of the petals. The following 4 different flowers have been observed:

1.    4 large black blobs with a white border at the outer edge
2.    4 black blobs (various sizes) without a white border at the edge
3.    2 quite small blobs (other 2 missing)
4.    No blobs at all

The most common are (1) and (4) from the above list. There is a tendency that the flowers with blobs are on average larger and contains numerous and more pronounced stamens from those without blobs. [SM].

Another variations is the colour of the stalk and bud bristles. In some species the bristles are just white, while in others they are purple-red [SM].
