Bryony is a climbing plant
There are a couple of British wildflowers that are labelled as Bryony: there’s White bryony Bryonia dioica mentioned here, and Black Bryony Tamus communis, which is a member of the yam family. Both are climbers, but White bryony is a member of the gourd family.
White bryony – Bryonia dioica
I don’t remember seeing this plant until June this year, then I saw it twice on the same day growing next to the road in Seaford, about 500m apart. It is common in South East England apparently. I saw it at shoulder height growing up a school’s conifer hedge, then again in the pavement at the base of a wall, as shown below. The foliage reminded me of Passionflower leaves. The flowers were about 2cm across and creamy in colour with five petals and green veins.
At the time of writing there are no posts mentioning Bryony, but I spotted it the same day I went looking for Twayblade orchids.
