Back in spring 2021.  1 litre sized pot.   Helenium Waltraut is a hardy herbaceous perennial with low green foliage and tall stems topped with flowers that open yellow and age to a golden red-brown.  Wonderful feature in the summer/autumn garden and loved by bees and beneficial insects.  Likes full sun in well-drained soil.  Reaches 80cm +, with strong stems that do not require staking.
