Small Plant Big Interest

New Zealand Bitter-cress (Cardamine corymbosa), as the name suggests, is a recent arrival to these shores and was recorded for the first time in 1975 in Edinburgh. Since then it has spread rapidly across the UK, so it is no great surprise that it has finally turned up in Huntingdonshire. It is an annual species that can be found as a horticultural contaminant, spreading via potted plants from garden centres to gardens. Peter Walker sent me these photos in April to identify, earning himself a new county record in the process.
