Bearing more than a passing resemblance to Herb-Robert, Little-Robin is a very rare species which is only found occasionally growing in the South and South-east. It has flowers which are smaller than those of Herb-Robert, measuring only 7-12 mm across. Apart from the difference in size, the main distinction between the two species is that the anthers are yellow in Little-Robin whereas they are orange in Herb-Robert. It bears stiff, alternate leaves which are deeply lobed and similar in shape to those of Herb-Robert. It is a much-branch annual, reaching about 15-20cm high, and blooms between May and September. The fruits – which are also similar to those of Herb-Robert – are more wrinkled in this species. Little-Robin grows in rocky, stony places, grassland, disused railway lines and on shingle beaches. It is a native plant and it belongs to the Geraniaceae family.
My first – and only - record of this species is from June 2014 when I saw and photographed it growing near Campile, Co Wexford. I had been told where I might find it by Paul Green, BSBI Vice-County Recorder for Waterford and Wexford. Many thanks, Paul, as ever.
