Found this also- The seeds (about the size of a pin-head) are naturally sown by the pod blowing in the breeze and shaking like a pepper-pot, the contents scattering. When deliberately set, they are either broadcast or dropped in rows of shallow holes made by a stick or dibber, the timing of the sowing depending heavily upon local seasonal and climatic conditions. About 500 grams of seed are sown to half a hectare. The seeds may range over a wide variety of colours from white through yellow to brown, grey or black, the coloration not being relevant to the eventual blossom. Other cash crops, such as beans, peas or tobacco, may be planted alongside the poppy: these do not hinder it and are usually only a means of obtaining a higher return from the same area of land.
The seeds germinate quickly in warm, moist conditions and, within six weeks, the plant is established by which time it vaguely resembles a young cabbage with glaucous, green leaves with a dull grey or bluish tint. By eight weeks, it reaches a height of about 60 centimetres and consists of a main stem the upper portion of which (the peduncle) bears no leaves or secondary stems. Below the peduncle, secondary stems (called tillers) may appear from leaf bases where they join the main stem. Apart from the peduncle, the stems are frequently covered with hairs.
As the plant matures, it grows to a height of between 90 and 150 centimetres, the leaves appearing alternately, those on the main stem being oblong, tooth-edged and between 10 and 40 centimetres long. The main stem and each tiller ends in a single flower bud. As these develop, the ends of the peduncle and tillers extend and bend over to form a distinctive hook shape, the young buds suspended upside down. However, as the buds mature the stems straighten, the main bud at the head of the peduncle pointing upwards. Within two days of becoming vertical, the sepals of the bud - which are the same colour as the leaves - open and the flower blooms. In ideal conditions, the main blossom appears around the ninetieth day from germination.
At first, it appears crumpled, like a butterfly emerging from its chrysalis, but the four petals quickly expand and smoothen, each marginally overlapping the other. Their colour may vary from plant to plant. Traditionally, opium poppies are white but they may just as readily be pink crimson, weakly purple or a variegation of these with the colour darker at the petal base. Inside the flower is a ring of anthers on top of what will become the pod. Fertilisation is carried out by insects.
The flower is short-lived. In two to four days the petals drop, exposing a small, round pod the size of a large pea. This rapidly grows and may become ovoid or globular: when mature, it is the size of a small hen's egg with a diameter of between 5 and 7.5 centimetres. It is bluish green with a slightly waxy appearance, the top surrounded by a small crown from which the stigmas rise. Where the pod joins the peduncle is a ring of petal base scars.
The pod is made of an outer skin enclosing the wall of the ovary, which is made up of three layers, and cavities or segments separated by seed-producing walls. The seeds, of which one pod may produce over 1000, are reniform in shape with distinct reticulations. When mature, they are loose in the pod before dispersal through small holes which open just under the crown.
