I found this flower growing by the path around the corner from our house. I've never seen anything like it before.
It was found growing in sand opposite a wetland in Perth, WA, Australia. The flower is about 1.5cm across and grows on a single long (~20cm) stem with hairy serated lancet leaves which are about 2.5cm long.
Thanks Michael's workmates and Urtica, I now know what this flower's latin name is. Wahlenbergia capensis or Cape Bluebell Which means this is an African invader and I can pick them with impunity;-)
