'KORbin' is a modern cluster-flowered floribunda rose cultivar. It is commercially available in two main forms: a bush and a standard, both produced by a form of grafting known as budding. The size and shape of bush forms depend on growing conditions and pruning regime: it is usually about 1.2 metres (3.9 ft) high and 1 metre (3.3 ft) wide, though in hot climates it can reach 2 metres (6.6 ft) high and if lightly pruned can become a graceful shrub. Leaves are small, light green and glossy. Blooms are about 5 cm in diameter and have 25 to 35 petals. They grow in clusters on long stems. Buds are long and pointed. The fragrant flowers usually appear abundantly throughout the year.
