John Bergmans seized the opportunity to bring order to the nomenclature of many new plant species.
His most important work, Vaste Planten en Rotsheesters (Herbaceous Perennials and Rock Shrubs, first published in 1924, and in a revised version in 1939) became a leading publication for growers and botanists. In 1974, the book was awarded the Veitch Memorial Medal by the Royal Horticultural Society. The original manuscript of the 2nd edition of Vaste planten en rotsheesters is on view at Special Collections also.
