Pimpernel (Anagallis arvensis)

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 an exotic plant (or weed)…

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 a weed.  So, it had…

Exotic (Weed): Large Quaking-grass (Briza maxima)

Also known as Blowflies, Blowfly Grass, Briza, Quaking Grass, Shell Grass and Shelly Grass, Large Quaking-grass is an exotic (weed).  I know this thanks to a local person I was fortunate enough to meet a couple of weeks ago.   We walked around the boundary and she shared her knowledge of plants native to this area, including grasses.  It was a wonderful morning and…

Wood-sorrel: Exotic or Native?

I’ve discovered there are two species of yellow flowering Wood-Sorrel (Oxalis) which look very similar, and are often confused.  One is native to Australia, the other is an exotic (weed) originally from South Africa. Looking at the flowers of both species, I believe this could be the Australian native plant Grassland Wood-sorrel (Oxalis perennans).  Can anyone confirm this?   For reference…

Exotic: Large-flower Wood-sorrel (Oxalis purpurea)

The Large-Flower Wood-sorrel flower looks pretty, but this plant is a weed introduced from elsewhere.  We have a couple of very small patches of it this year. 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 want to use poisons.  Does…

Centaurium Erithraea

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, that is not indigenous to…
