Often planted into the cracks in the sides of walls which it enjoys the best, from where it spreads of its own accord. It has plenty of drainage there, and usually much sun, which it can tolerate. But it can also grow in the shade. |

It seems to like the alkalinity of the mortar in the walls. Flowers yellow in short one-sided spikes. |

Leaves floppy and droopy, filling any available space to maximise light capture. |

This specimen with unusually long flower stalks with a short one-sided spike (a raceme) of flowers atop enjoying alkaline run-off from a concrete path. |

This is the more normal way for the plant to display its flowers. |

The flowers are long and tubular over most of their length apart from a short widening into petals at the front and a short bent-downwards spur at the rear. The flower stalk holds up the flower before the spur curls downwards. Flower mostly bright yellow, but young flowers can display a little green on the petals (and older ones turn orange at the tip). |

The flowers have a spur at the rear before the short flower stalk. On the left there is a long, thin, pale-green as yet immature seed pod. Ripe seeds are a dark-brown with a white fleshy elaiosomewhich covers part of the seed. The elaiosomes are fleshy structures which attract ants and it is they who transport and 'plant' more seeds in the wall making it spread many metres over some walls. Elaiosomescoat the seeds of many other plants sych as those of Greater Celandine, Bleeding-Hearts, Hyacinthsand Violets amongst many others. The flower stalks (petioles) have a short white bract near the main flower stem. |

The flower spikes are asymmetric, with flowers occupying less than a semicircle around the main flower stem. |

There are two very short but slightly wider petals, one above and one below the 'mouth' of the plant. |

Best seen on the flower lower right are two further crinkly yellow petals arranged like a mouth which is slightly ajar. Flowers c. 2cm long. |

The leaves are a bright greyish-green. |

Leaves in opposite paris apart from the terminal leaf. The leaves split into three leaflets, which are partially divided into 3 lobes, each lobe ending in a point (being in this case a hydathode (to expel any unwanted water). Each leaflet is often asymmetrical. |
Uniquely identifiable characteristics : There is no other plant quite like this. The Genus Pseudofumaria used to belong to the Fumariaceae (Fumitory) Family but has since been re-assigned to the Papaveraceae (Poppy Family). Residing in the Poppy family (Papaveraceae) it inherits a certain toxicity due to a combination of differing alkaloids.
Yellow Corydalis has asymmetric leaves reminiscent of those of Moschatel, Lesser Meadow-Rue and Pale Corydalis amongst several others.
