The Dahlia and Garden Mum Festival (ダリアとガーデンマム祭) is under way at Sera Kogen Farm (世羅高原農場) in Sera, Hiroshima, and dahlias and cockscombs (celosia) are now in full bloom. More dahlias are expected to open one after another over the course of the festival, so the display can be enjoyed for a long time. Autumn flowers, including the cockscombs, are also in full bloom, while the garden mums have just started to open.
Visitors are encouraged to check the bloom status on the official website before heading out.
