This beautiful plant was by itself on a very large mound of rubbish and I had only seen 2 others alongside the road over a distance of around 20 km and while there is a similarity to Patterson's Curse, which really grows berserk, there were none growing in the paddocks (fields). Oh well, perhaps someone can confirm. I spent quite a bit of time checking it out - to me it may not be Patterson's Curse. And the flowers were rather small. But the slight similarity is there.
May be Echium handiensis - thanks to Celeste for assisting with ID.
Do view large.
