When I first found these pretty blue flowers, a year or two ago, I thought they might be native. I put the photograph aside for identification, and got too busy to search for the species name. With the wet spring weather, it is plentiful again this year. Unfortunately, it isn’t a native Australian species, but … Continue reading Pimpernel (Anagallis arvensis)

Boxthorn (Exotic) or Bursaria (Native)
The original Post In a corner of our property, an area which has been slightly disturbed by small-scale mining in the 1800’s, I found a waist-high shrub with white flowers and thorns – Bursaria (native) or Boxthorn (Exotic) I wondered. It turned out to be Boxthorn, an introduced species which has the potential to become … Continue reading Boxthorn (Exotic) or Bursaria (Native)

I think it is new as I have not noticed it before. I’ve heard that Oxalis spreads if you try to pull it out of the ground and we don’t … Continue reading Exotic: Large-flower Wood-sorrel (Oxalis purpurea)
Exotic: Common Centaury (Centaurium erythraea)
This pretty flower has had my attention for a month or two now. There is a very small patch of them growing along the front fence. In Summer, when hardly any flowers are in bloom, it was a lovely show for a while. However, I’ve just identified the plant as an Exotic species, or weed, … Continue reading Exotic: Common Centaury (Centaurium erythraea)
