Climbing Corydalis bears quite small (4-6mm long) creamy-white flowers that are somewhat similar to those of Yellow Corydalis, but much shorter. These are tubular and zygomorphic, with 2 sepals and 4 petals and are grouped in short spikes. The bi-pinnate leaves are flat-lobed, much-divided and end in branched tendrils which help the plant to scramble and climb. The plant, which never grows beyond about 70cm, produces a mass of delicate foliage with the flower clusters appearing from April to December. Formerly known as Corydalis claviculata, this is a native, annual plant species which belongs to the Poppy or Papaveraceae family.
I first saw and photographed Climbing Corydalis in April 2018 when a very kind visitor to this website, Jill Stevens, told me about it and she even brought me to the spot where it grew in Killiney, Co Dublin. Thank you Jill.
