How can you get the plant name so wrong?
The errors start with me miss spelling the plant name when I took the photograph at least according to Google who want to see an ‘a’ after the ‘r’ to spell Centradenia. Now I think about it, did I copy the plant label correctly or had the wrong label been attached to the plant stood on it’s own on the capillary mat at the nursery?
More likely the problem is compounded as the plant looks very similar to a Petunia and as they say ‘if it looks like a duck and quacks like a duck it is a Petunia’.
Would the nursery have used such a truncated name even with an ‘a’? If Google were right then the full name should possibly be Tibouchina heteromalla “Purple Glory Bush” or similar species of the Myrtle family . Widely attractive to humming birds, of which we get virtually none in the UK.
