Large violet-blue flowers with a deep red central bar. Purple-red stamens. The hybrid is probably named after the ballet 'Kamennyi Tsvetok' by Prokofiev which translates as 'stone flower' or 'jewel flower'. Can be treated as a group 2 (tidy up only) or group 3 (hard prune). If it is hard pruned it will be at the expense of the early flowers on old wood the following year.
