What is this? It had blue or purple flowers in early summer

  • Which is it: blue or purple? What did the flowers look like? Where in the world did you find this plant, and what conditions was it growing in?

  • Small blue flowers I think, in early summer. London UK. Shady conditions in garden. Photo taken 29 August 2017. Aug 29, 2017 at 20:21
  • Are the leaves rough and unpleasant to touch?

  • Need to have scale reference, please? If the ivy is a normal ivy these leaves are huge?

On the assumption the leaves are rough and unpleasant to handle, it's Pentaglottis sempervirens, common name green alkanet, a common perennial 'weed' in the UK, and difficult to dig out or eradicate (because of its deep, yet fragile roots) once established. Image and info here: Green Alkanet (Alkanet, Evergreen Bugloss) .

  • I'm not sure about the identification. This plant remember me something.. Aug 30, 2017 at 6:58
  • @GiacomoCatenazzi - reminds you of something? Digitalis purpureum or Borago officinalis possibly - its not Digitalis if it has rough leaves, and Borago, (which it could conceivably be), is only an annual - without flowers, hard to be 100% between alkanet and borage, but I'm betting its alkanet, given where the OP lives

  • I think it is green alkanet. I looked at pictures and seem to recall the small blue flowers. Aug 30, 2017 at 12:28
