Unique is a large shrub which will grow to 3m. The flower heads of ‘Unique’ can reach 30cm long by 20cm wide with a mix of small fertile florets mostly hidden by the sterile florets made up of very showy sepals which can grow to 5cm across. Jelena and Robert de Belder at Arboretum Kalmthout introduced ‘Unique’ in 1968 because of its large and pure white sterile florets. They flower later than most, approximately in August for our plants. Tales of its origins are colourful and there is disagreement over its identity. Our plant was purchased at Hillier’s Arboretum in 1984. Hillier’s is believed to have the original form which is now sometimes known at ‘True Unique’.
