@marlboromaam Hi Mags. Apparently, there are different toadflaxs - I've only found out its name this morning. The site also showed some very showy, larger yellow toadflax plants - quite different to these. Maybe they are yours. :)
@marlboromaam Ahh - thanks so much for the link - that looks so very similar to ours. Ours may be slightly more blue in tone - but so similar in the structure of the flower. These individual flowers are also very small, but spread along a single stalk of about 10 inches long. Maybe about 10 or more flowers on each stalk. They are lovely. Thanks again so much for the photo and info - so interesting. Cheers Rob
