Yellow corydalis

Enw gwyddonol: Pseudofumaria lutea
Yellow corydalis is a familiar 'weed' of gardens, walls and rocky places. It is a garden escapee in the UK, so is not a native plant. Try choosing natives for your garden to prevent species escaping into the wild.

Sut y gall bobl helpu

Our gardens are a vital resource for wildlife, providing corridors of green space between open countryside, allowing species to move about. In fact, the UK's gardens provide more space for nature than all the National Nature Reserves put together. So why not try planting native plants and trees to entice birds, mammals and invertebrates into your backyard? To find out more about encouraging wildlife into your garden, visit our Wild About Gardens website: a joint initiative with the RHS, there's plenty of facts and tips to get you started.
