Which has smaller flowers, Campsis or Kalmiopsis?
Campsis Campsis (trumpet creeper, trumpet vine) is a genus of flowering plants in the family Bignoniaceae, native to woodland in China and North America. It consists of two species, both of which are vigorous deciduous perennial climbers, clinging by aerial roots, and producing large trumpet-shaped flowers in the summer. They are hardy but require the shelter of a warm wall in full sun.
Ichtyoselmis Ichtyoselmis macrantha (also spelled "Ichthyoselmis"; formerly known as "Dicentra macrantha"; large-flowered dicentra) is the only species in the genus Ichtyoselmis. It is a perennial plant growing from a long rhizome, native to woodland and glades at elevations of 1500 - in northern Burma and southern China.
