I have had Brugmania before which never wintered that well due to lack of air flow around them . They rotted rather than the cold getting to them.
But this years catalogue brought plant seemed to grow well from the small thing that arrived thru the post back in May but has Failled to produce a single flower & I'm guessing mid to late August regardless of variety I might have been sent is to late in the season for it to start now ??
Any idea's what went wrong ???
