A group of hybrids thought to have originated from the crossing of A. discolor var. mollis (q.v. under A. pavia) and A. neglecta or its var. georgiana. The type was a garden tree, first described in 1834. The following forms of the cross are in commerce:
cv. ‘Harbisonii’. – Undersides of leaves hairy when young and somewhat glaucous. Flowers bright red, in panicles 6 to 8 in. long, borne in May and June. A shrub of little garden value in the British Isles. It arose at the Arnold Arboretum among plants raised from wild seed of A. neglecta var. georgiana.
cv. ‘Induta’. – This hybrid arose in Hesse’s nurseries, Germany, and was originally known as A. rosea nana. Leaves hairy beneath; flowers pink, with yellow markings, borne in May and June more abundantly than in most of the American buckeyes. It makes a large shrub in time, and was given an Award of Merit when shown by the late Sir Henry Price, Wakehurst Place, Sussex, in 1959.
