Clematis Josephine taking over my garden and reverting to wild type
I bought and planted Clematis Josephine (as above label), in May 2012 to try to cover a nasty fence (see photo). However, after planting, it failed to flower in 2012, and again this year. Instead, it has produced an absolute mass of foliage, smothering all the other plants in the border. After hacking some back to get some light to my attempted espalied an apple and plum tree also on the fence in June, it continued to go completely bonkers foliage wise. It has now produced some tiny, white flowers
What has happened to my clematis? Has it reverted to 'wild' type? Did I buy a mislabelled plant?
Will it ever produce the double blue Josephine flowers?
I need to decide whether to dig the whole plant up, as it is completely smothering all the other plants in my border.
