Was given this as a miniscule cutting and told it was Penstemon. Have nurtured it, but it looks nothing like my other Penstemons. Can anyone identify it or have I been cosseting a weed?
Have kept this over winter and I think it is leysesteria formosa, as it is similar to one in my neighbours garden. So guess the Penstemon didn't make it. This looks quite vigorous so wondered whether it needs sun or whether I could put in it a shady but bare part of my garden. Any thoughts very welcome please.

Sun or shade.
