....It was then north to the nursery and garden of Philip Robinson and Greg Lowery at Santa Rosa....Philip's 'Variegata di Bologna' had sported back to a luscious purple flower of great beauty and mine has done the same. I have consulted all the old books from 1909 - the year of introduction and there is no mention from what 'Variegata di Bologna' sported. Tentatively I have called my sport Purpurea di Bologna better I think than Non Variegatea di Bologna.
