PLANT PROFILE


Knautia macedonica

Knautia macedonica

Crimson Scabious

A genus of summer-flowering annuals and perennials, Knautia has interesting double pincushion-type flowers that show its close relationship with Scabiosa. Its interesting foliage and wonderful raspberry-red colouration make it a great addition to any perennial border. The most commonly available form, Knautia macedonica, has already become one of my garden favourites. The strappy foliage in the image above is from a nearby Siberian Iris.
