The reserve flora includes Common Meadow-rue and Great Burnet which is typical of old, unimproved neutral meadows.

These environments contain many rare meadow and aquatic plants including meadowsweet, common meadow-rue, hemlock water-dropwort and golden-saxifrage.

Common meadow-rue (Thalictrum flavum)

The larvae feed on Common Meadow-rue, Lesser Meadow-rue and Great Fen-sedge.

Flourishing uncommon species include Fine-leaved Water-dropwort, Common Meadow-rue and Cyperus Sedge.

Jelitto also offers Thalictrum flavum ssp.

On the edge of the tall fen, the locally scarce meadow rue, Thalictrum flavum, is plentiful.

Common meadow-rue (Thalictrum flavum)

The western bank is relatively undisturbed and supports a richer assemblage, in which the locally scarce common meadow rue, Thalictrum flavum, is abundant.

Larva live in a thin silky spin between the leaves and flowers of Thalictrum aquilegiifolium, Thalictrum simplex and Thalictrum flavum.

The larvae feed on Thalictrum species, such as Thalictrum flavum and Thalictrum aquilegifolium and Aquilegia vulgaris.

Locally uncommon plants include Meadow Rue Thalictrum flavum, Brown Sedge Carex disticha, Water Violet Hottonia palustris, Whorl-grass Catabrosa aquatica and the carnivorous bladderwort Utricularia australis.

In the Asian Subcontinent, the spores cannot survive the hot dry weather but are re-introduced every year from the Himalayas or surrounding hills, possibly coming from Berberis spp, Thalictrum flavum and Muehlenbergia huglet which is a main reason for bread mouldes or even some grasses.
