What is this plant?

bertrand-mabel

We have this plant growing under Azara serrata. We didn't plant it but it is a very nice plant.

We thought that is was a verbascum but now that the flowers are there it doesn't match up to any verbascums in our wild flower books.

You can see from the photos that the flowers are single and in the axil of the leaf not only long spire.

Any ideas?

Many thanks

Oenothera macrocarpa, Evening Primrose.

We have these also in the garden and the plant looks nothing like evening primrose.

I think @Palustris may be right as oenothera macrocarpa is not the same as common Evening primrose - oenothera biennis.

There are several types of Evening Primrose

Looks like Verbascum phlomoides to me.

That's another possibility tho I'd have expected tighter flower spikes.  maybe that's cos it's in shade.

Thank you all.

The oenothera macrocarpa is described by the RHS as a prostrate plant. This certainly isn't and the leaves don't look the same.

With the verbascum the flowers are all in one spike whereas this one has single flowers in a leaf axis.

We have some more growing on the other side of a fence and in the sunshine so hopefully we will be able to see if the flowers do conform to the verbascum.
