This so called false sunflower is very valuable for their long season of bloom. It started to flower in July and is still looking good. Weren't so much rain recently, it would probably look even better. The colour is bright yellow, like a sun as it name suggests, coming from the Greek 'helios', the sun.
This cultivar forms medium-sized bush with plenty of flower heads. Dead-heading prolongs the flowering season. The plant loves sunny position but it doesn't seems to mind either heath or high humidity.
The flower head is full of frilled single flowers making lovely pompoms. I have learned that the plant self-seeds if allowed to bare seeds so I am going to collect some in autumn.
