I'm sorely tempted to suggest a white pelargonium, commonly but
incorrectly called geranium, but the leaves aren't right.

Another reason why it's not a pelargonium is that the flowers of
sympetalous (petals fused together) rather than choripetalous (petals
separate).

I make the floral formula K(5)C(5)A2+2G1. Googling finds me a database
of floral formulae by plant family
(http://www.bakoma-tex.com/doc/latex/...r-ex-en-x.pdf), which
tells me that this is Scrophulariaceae. There are relatively few
Scrophulariaceae with zygomorphic (radially symmetric) flowers, and some
googling leads me to Chaenostoma cordatum, also known as Sutera cordata
and Bacopa, which is a common hanging basket plant.
