Hi folks
I do not want to disillusion you but that plant is not as nice as it seems.
Let me first say that this is a 'macro' shot so appears to be quite large like a marigold but in fact is only about ¾" across.!
Here are a few shots I took of the plant tonight thus proving it is a weed that has self sown itself into my wall .
This is it tonight as a 'point & shoot subject (sorry for the quality but I think you will see what I am getting at)
Same flower head approx 24hours later.
This is where it has self seeded into: The hole is only about ¾" across.
Now I have had a request for seeds which you can have if it sets seeds but I do not know if they would be viable as I do not know if has been pollinated. Plus the fact there is only one plant at the moment although it looks like an other couple are on the way.
Personally I agree with Ace
