Hello all:
Been on sabbatical for a bit; sorry I'm late to the ID gala - but glad to be invited (@porkpal)...
That is undoubtedly a Viburnum x pragense - Prague Viburnum. Its parentage is Viburnum rhytidophyllum x Viburnum utile. I wish it had a better common name, because it is a fabulous plant. Very easy to grow in the eastern US, the narrower evergreen glossy leaves are handsome year round, and set off the very lightly fragrant flowers every spring. The leaves have very silvery undersides, too, which can also be an attractive quality.
This viburnum grows into a "haystack" mounded shape, maybe 10' tall by 6' wide (3m x 2m) or thereabouts. It is increasingly being used as a large hedge around Kentucky. It has defoliated with winter temperatures below -15F, but that is rare around here and probably never in Richmond VA.
As far as a partner for pollination: I have grown over 125 taxa of viburnum here at the Valley over the last 30 years or so. V. x pragense will set some fruit, but will never have showy quantities. You will want to plant one of Prague Viburnum's parents, or a hybrid with one of its parents, in order to achieve the cross pollination. Key is to have that other plant blooming at the same time.
If I had to name plants - and I relish doing so - I would suggest:
**Viburnum rhytidophyllumI and clones (like 'Cree')
**Viburnum x rhytidophylloides and clones (like 'Alleghany')
**Viburnum x burkwoodii and clones (like 'Mohawk', 'Fulbrook')
**Viburnum x 'Chesapeake'
**Viburnum x 'Cayuga'
**Viburnum x 'Conoy'
**Viburnum x 'Eskimo'
**Viburnum x 'Nantucket'
**Viburnum x 'Pearlific'
**Viburnum x 'Susy Dirr'
You should research the characteristics of these selections, as they range through deciduous and broadleaf evergreen, range widely in overall size, and can be amazingly fragrant to solely smelling white.
BUT...you can never have too many viburnums.
