Czech Republic, June 2009. In summer flower. Very good reblooming (remarkable autumn flowering), better planted in tight groups of three to make one better shrub. Scented. Very blackspot prone in my conditions.
Czech Republic, November 2008. Autumn flowers - their shape and colour can vary in this time according to specific conditions (these are from a quite shady place).
