Ceratocapnos claviculata Climbing Corydalis C DD N
I don't often disgree with the Prof Stace but these plants, of which there are thousands growing close to home most certainly aren't annuals nor do they necessarily grow in shady places. One of the biggest colonies of Climbing Corydalis locally is on top of Helsby Hill on the Iron-Age Fort ramparts where hundreds of plants grow. It flowers in Spring but there are usually some flowers to be seen at most times of year even in the depths of winter. It will grow on extremely acid soil and in shady conditions so it can be found in the dark under conifers for instance.
This is a common plant which grows most abundantly in Wales but is common in England and Scotland except for the central highlands and far north. In Ireland it is uncommon and usually found in the east.
