I've had this shrub in my garden for a while and always thought it was called Rhodotypos scandens which I think is in the rose family. But just noticed that all the flowers seem to have four petals, not five like rose family normally have. Have got its name wrong or can rose family have 4 petals sometimes. I do know Rhodotypos is unusual in rose family for having opposite buds.

I think you are right to call it Rhodotypos scandens.

For every rule in existence there is an exception ;)

Many thanks both of you

I grew one from seed and had it for many years. Recognized your pic immediately.

Good for you that you grow something off the "beaten path".
