Andrea B. Posted February 24, 2020 Share Posted February 24, 2020 At first, the flower looked rather plain in UV. But then I saw that cool little purple stripe. Pollinators must be careful with this flower! Link to comment

Andrea B. Posted February 27, 2020 Share Posted February 27, 2020 Dave, that is a *wonderful* newsletter - and so beautifully illustrated. Your Australian Native Plants Association has quite an impressive list of study groups. I looked at some of the Eremophilia profiles and more. Link to comment
