The description page says this is "a Hybrid Gigantea" but I can't see anything in the references here to support that. Is there some other reference to Gigantea blood not included? I can see similarities with 'Hadley' and 'Princeps' in 'Editor Stewart', so I'm wondering is it's one of Clark's favoured seed parents pollinated with 'Princeps'.
The fact that it was recommended as a hedge suggests it must have had a degree of retention of its foliage in winter. So perhaps there is Gigantea in it after all.
Also, to anyone who has experience of 'Editor Stewart', does it produce hips?
