Description
Corydalis cava is a tuberous woodland perennial prized for its softly scented, mauve-lilac flowers that appear in early spring. Each stem bears a loose spike of tubular blooms above finely cut, fern-like foliage that dies back after flowering—true to the ephemeral woodland bulb form.
Native to central and eastern Europe, this species thrives in moist, humus-rich soils and is particularly suited to Irish conditions where damp winters and cool springs promote strong growth. It naturalises well in undisturbed, dappled-shade areas and pairs beautifully with other spring ephemerals like Anemone nemorosa, Erythronium dens-canis, or Leucojum vernum.
Corydalis cava is ideal for early-season biodiversity, attracting bees and hoverflies, and is valued in rewilding schemes and heritage-style woodland gardens.
