This is the thirty first year of the international competition focusing on new rose varieties. The venue is regularly attended by cultivators from Germany, France, Belgium, Denmark, Holland and England as well as New Zealand, Ireland and the USA. The displayed exhibits enhance ideas about a surprisingly wide range of shapes and potentials for the use of roses, these beautiful flowers, both ancient and modern. The Rosarium will be also open on Jun. 29 – 30, 2013.
