Flowering plant

I have had this plant for a number of years and it seems to thrive on neglect. This is the first time it has flowered. It has 2 flowers.

Catching up on chores today after long weekend away. The bird feeders were almost empty even though I filled them before I went away. The great tits, chaffinches, coal tits and sparrows are constantly coming back and forth getting food. They must have nests nearby. There is one great tit in particular who is moulting as well, poor thing.
