Only found in the south-west and west of Ireland, this prostrate perennial is related to Cleavers and other Bedstraws. It creeps across dry grassland and limestone soil on thin, much branching stems. The tiny pale pink 4-petalled star-shaped flowers (3-4mm across) are borne in dense, terminal clusters from June to September. The bright green, linear leaves are carried in whorls of 4. This is a native plant and it belongs to the Rubiaceae family.
I first identified this wildflower on a very overcast, squally and damp day at Black Head, Co Clare in 2004 and I photographed it at that time. I hope to get back there soon to get a better photo.
