Ecology

An annual of arable crops, usually found on field edges and in unsprayed corners, often in small numbers. It is most frequent on light sandy, gravelly and chalky soils. Rarely, it occurs on waste ground. Lowland.

Status

Archaeophyte

World Distribution

As an archaeophyte P. argemone has a European Southern-temperate distribution; it is widely naturalised outside this range.

The normal habitat for this species is arable field margins, mainly on poorer, light, sandy and calcareous soils in south and east England. It also occurs rarely on open waste land and railway banks in lowland areas. It is commonly associated with P. rhoeas, and occasionally with P. dubium or P. hybridum. Other common associates include Anagallis arvensis, Anthemis cotula, Aphanes arvensis, Chaenorhinum minus, Euphorbia exigua, Fumaria densiflora, F. officinalis, Galium aparine, Lamium amplexicaule, Legousia hybrida, Matricaria recutita, Myosotis arvensis, Petroselinum segetum, Polygonum aviculare, Reseda lutea, Stellaria media, Valerianella dentata and Viola arvensis.

An annual which germinates in autumn and spring, it is best represented in autumn-sown crops. The flowers are normally self-pollinated. In conditions where there is strong competition from other species, few seed heads develop. Seed dispersal is rather poor as many seeds remain in the capsule after ripening. Seed is capable of retaining its viability in the soil for some time, and germination is sporadic, being dependent on the erosion of the seed-coat.

This is a lowland species which in Britain has become rare in the south-west and occasional in most other areas of its former distribution. Although it is still locally frequent in the south and east, it is normally found in small numbers. It is susceptible to many herbicides, including some of the earliest invented. It is unable to tolerate competition with heavily fertilised modern crop varieties, and is usually found at the edges of fields or in unsprayed corners.

It is found throughout lowland Europe (Jalas & Suominen 1991) and eastwards to the Caucasus, Iran, Palestine and Cyprus, but it is generally introduced and of casual occurrence in the north, where it reaches Scandinavia. The centre of origin is possibly in the eastern Mediterranean.
