1: The flowers on our streets

Isabel Hardman presents the first in a new series of the Wild Flower (Half) Hour podcast. She meets Sophie Leguil, who runs the More Than Weeds campaign, and hears from BBC presenters Chris Packham and Martha Kearney about their favourite wild flowers. Rebecca Wheeler introduces the challenges for the next two weeks of #wildflowerhour and Leif Bersweden takes us on a wild flower walk.  To find out more about #wildflowerhour, visit our website.
