Wild Iris

Patersonia sp. (either P. sericea or P. glabrata)


These are Australian native wildflowers that can grow in the harshest of conditions. There are two species to choose from but I can't tell them apart - Silky Purple Flag, and Leafy Purple Flag. Both species are native to Australia's eastern coast. Patersonia is a densely tufted grass-like herb with tough, stiff leaves. The leaves of each plant are arranged in a line on either side of the flower stem. The flowers range from blue to purple and have 3 broad sepals, 3 smaller petals and 3 yellow stamens. They are delicate and short-lived, opening one after another on sunny days. They looked really cool amongst the large granite boulders.


Spotted in native bushland in Girraween National Park, along the Pyramid Track. Remote, lots are granite boulders, very sandy soil. Some were fully exposed to the sun for most of the day, whilst others were well shaded. In this area, enormous extremes between day and night temperatures. Here's some park info -


Two links I found that show each species. Can you tell them apart? I'm inclined to think this spotting is P. sericea, but am not 100% sure. http://www.friendsoflanecovenationalpark... and http://www.friendsoflanecovenationalpark...
