white-flowered evergreen twining vine

[Diane Whitehead]

This vine is growing at the base of an Irish yew, and has twined itself about four metres high.
It is in flower now.
The leaves are opposite, three cm long.

I guess this is Euonymus fortunei

Thank you, Gerd.

I've looked it up and this is what I found:

"the most widespread and polymorphic of all the Euonymus species, found across the entirety of Asia"

It has orange berries so a bird probably dropped a seed under my tree.
