Clematis back from dead.
Hi, I was tidying up the garden yesterday and was amazed to discover that a clematis that I planted about 8 years ago has re- grown itself through my shrub border. It 's a duchess of edinburgh and I know now that it is a difficult one to establish so thought that may be the reason why it died. Not only is it growing well but has 2 big flowers on it . It's growing through a euonymus alatus and looks quite healthy. Is this unusual and can I expect it to live ? There's a lot of shrubs packed around it and I can't see where the roots are and can't remember where I planted it. Thanks.
