Small Toadflax is not easily confused with other wild plants on this web site.


Small Toadflax is a slender, downy annual which grows in arable fields, on dry banks and walls and along railway tracks. It’s a branched plant which bears small, pale lilac-coloured flowers (6 – 8 mm) solitarily in the leaf axils. Each two-lipped flower has a slightly-open mouth with three clearly-defined lobes on the lower lip and two above. There is a slight yellow flush around the opening and a short, blunt spur to the rear. The grey-green leaves are linear-lanceolate and they taper into short stalks.  Flowering from May to October, it rarely grows taller than 25 cm. An introduction into Ireland, it belongs to the Veronicaceae family. 

I first recorded this wildflower growing near Athy, Co Kildare in 1978 and photographed it at the National Botanic Gardens, Glasnevin in 2010.
