| Baarn, The Netherlands |
'Commelin' was one of two Dutch hybrids released for sale in 1960. Raised at Baarn by the Willie Commelin Scholten in 1940 from a crossing of Ulmus × hollandica 'Vegeta' and a selection of Ulmus minor from the Barbier nursery, Orleans, made in 1929. It proved a fast-growing, attractively-shaped tree resistant to wind and a range of elm ailments. Distinguished by its narrow habit and small leaves, it enjoyed considerable commercial success and over 500,000 had been sold by 1974. Unhappily, the tree had only been screened for non-aggressive or semi-aggressive isolates of the causal fungus of Dutch elm disease. When its low resistance to the new, aggressive strain of the disease became apparent, sales plummeted, and only 500 were sold in 1990.[1][2] Fortunately, neither 'Commelin' nor its equally vulnerable contemporary 'Groeneveld' had sold in great numbers beyond the Netherlands, although it was later used in hybridization experiments in the USA as female parent of several cultivars.
