Two very pretty ivy leaved pelargoniums you might think and indeed they are very pretty but it is in fact one plant – most bizarre and I really don’t understand it.  I have had a good check and it isn’t two plants in the same pot or anything like that. It could be that the whiter flower will fade to the darker colour but I am sure I would have noticed this before; although having decided to give up the plot I do feel as though my eyes are opened a fresh to the garden. There is one clear stem coming out of the pot splitting into two stems and one has a bright pink flower and one the whiter flower.

I really don’t understand how this happens.  Could it be that the plant being stressed may have caused it? Could the wet weather and lack of real heat/sun be a reason?
