Marigold Corn is not easily confused with other wild plants on this web site.

This is an extremely attractive wildflower which grows commonly on arable land, roadsides, and cultivated, lime-free soil.  It is an annual which grows to about 50cm high and whose greyish stems bear solitary golden yellow flowers (30-50mm across) The daisy-like flowers, which bloom from May to October, have flat, golden-orange centres of disc florets which are surrounded by broad, overlapping deep yellow ray florets. The lower leaves are fleshy, pinnately lobed, alternate and stalked, the upper clasp the stem.  This plant is thought to have been introduced to Ireland and it belongs to the family Asteraceae.

My first record of this wildflower is from 1978 when I found it at Newcastle, Co Wicklow and I photographed it thirty years later near Greystones, Co Wicklow.

The sight of a mass of these beautiful golden daisies was not always welcome through the centuries.  Considered a serious weed, farmers were very heavily penalised in the Middle Ages if found to have this plant among their crops.  Probably introduced into our island in the Iron Age, it was an enormous pest as it grew in among the native cereal crops and it was not until the 1970's when an effective herbicide joined the battle, that the plant started its decline.  However, its seeds can lie dormant over quite long periods waiting for the ground to be 'developed' and so re-emerge to light up the waysides. It is much loved by bees, moths and butterflies.
