Marsh pennywort
Marsh pennywort is widespread throughout the UK, but scarce in the south-east of England, where drainage and development have eliminated many sites.
However, it is still widespread in the New Forest. It will grow in any wet habitats that are not too shaded, but will also tolerate light woodland. You can find it on almost any walk that goes past damp areas – try looking carefully around the edges of Hatchet Pond. The characteristic leaves are present all year and the tiny flowers are out in June and July.
