I have a beautiful and very full Clematis Jackmanic. This year it has small white flowers growing off the same stem as the purple flowers. What would cause this? thank you, Chris

Could they be the unopened flowers which are of a white colour and an oblong shape or perhaps even seed heads?

It would be interesting to see a photo if you can manage it.
