my last plant to flower this year from the Pseudocodon group: Codonopsis vinciflora or Pseudocodon vinflorum. this is a first flowering for this species.
this plant was very slow to get going in spring, but is now perhaps showing more vigour. its flower buds do not have the sepals fused around the corolla
the flower stalks are thicker and longer, which means that the flower stretches upwards. there are no velvety hairs in the centre and no violet rings. it is a more intense violet-blue.
