Verbascum 'Christo's Yellow Lightning'

Found in Eastern Turkey when Christo (the late Christopher Lloyd) was on a trip with Great Dixter head gardener Fergus Garret and tulip expert Anna Pavord. They came across a man leading an elderly donkey as it laboured feebly along a rocky path loaded down with a towering load of verbascum stems. Christo asked Fergus (who speaks Turkish) to ask the man the name of the donkey and it turned out the donkey was named Lightning.  So it was natural that the verbascum that came from the trip was called 'Christo's Yellow Lightning'. Densely packed pale yellow flowers on multi-branched stems.
