I see it on my walk to work. The tallest stem is approx 27 in/70 cm in height and the flower seems to be an odd cone shape (?). It spends most of its day in the sun. These pictures were taken July 10, 2015.
Welcome to the forums! It is Linaria vulgaris. https://www.google.co.uk/search?q=l...Sp7Aa0_o_QAQ&ved=0CAcQ_AUoAQ&biw=1536&bih=728 https://en.wikipedia.org/wiki/Linaria_vulgaris
