Van Moorsel A1 - Rutger Barendse SP - 15 EP - 24 AB - Cardamine corymbosa in nurseries and gardens, a recent addition to the alien flora of the Netherlands and Belgium. Around 1975, Cardamine corymbosa Hook.f. was introduced to the British Isles, most probably with nursery plants imported from New Zealand. Some years later it appears to have crossed the North Sea and is now spreading in the Netherlands and Belgium. An overview of records for both countries is given, together with notes on its identification, ecology and potential as an invasive alien following exchanges between nurseries, plant centres and gardeners. It is shown that so far only little information about its introduction and spread has been exchanged between botanists and horticulturists. VL - 93 ER -
