I saw this pink and white Convolvolus or Bindweed growing through a Laurel hedge the other day. I was knocked out with it's beauty and trumpet shaped flowers.
I remember white coloured Bindweed flowers when I lived in Blighty. But I can't remember seeing pink and white ones.
Apparently they can be toxic to livestock if they graze them.
Incredibly they are related to the cultivated garden flower Ipomea or Morning Glory.
Perhaps the Gallagher brothers were inspired by this flower when they visited their ancestral home in Ireland. The Bindweed flowers certainly inspired me. Drop dead gorgeous wild flowers!
