Comfrey, part three. Symphytum 'Hidcote' is a stoloniferous spreader and a clumper. 'Hidcote' is a reference to the garden at Hidcote Manor in Gloucestershire I believe, presumably where this variety originated or was first identified. It's described as the cross between three species of Comfrey: Symphytum officinale x asperum x grandiflorum.

 I planted both 'Hidcote Pink' and 'Hidcote Blue' but the form with a wash of pale blue on the white flowers seems to have become dominant.
