I did not go on a deliberate hunt for these flowers. They just happened to be where I was and I was attracted to them especially because:
I have never seen them before.
Weidelia trilobata (Yellow creeping daisy)
They were purplish in colour. In this case not only the flowers but the leaves as well. Loropetalum chinense (Chinese fringe flower)
They came with interesting leaves. Laurentia longiflora (Star of Bethlehem) that originates in the Caribbean.
