Pests and diseases
Although resistant to the original strain of Dutch elm disease, Ophiostoma ulmi and a range of other ailments, 'Commelin' proved very susceptible to the later, aggressive strain Ophiostoma novo-ulmi subsp. americana.
Cultivation
'Commelin' initially enjoyed considerable commercial success and over 500,000 had been sold by 1974. However, 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 strain of the disease became apparent, sales plummeted, and only 500 were sold in 1990.
