Does anyone know what the shrub is this? The closest match on flowers I found was Acronychia. However, leaves do not match. Thank you.
Have you ruled out Cornus? To rule it out have you tried the leaf test? See... http://www.landscapejuice.com/2007/09/how-to-identify.html
Perfect! Thank you, Silver! This is definitely Cornus alba, or Tatarian Dogwood, native to russian region Tataria. The shot is from my friend from Moscow, so I could not do the leaf test. But both flowers and leaves fit now, including the white edge on the leaves.
