SK 3397 10 April 2022: 4 high res. images.

Location: National History Museum, London 
Altitude: 10m.
Date: 27 March 2022
Habit : Cultivated
Viburnum… ???


It is Cornus alba sibirica… common name Dogwood.

Opposite leaves.
Leaf veins are correct. 
4 petal flowers.
With leaves so pale it may well be Cornus alba sibirica aurea.
If in doubt as to whether it is Cornus always try the leaf test… see my pics below
Gently  tear the leaf across the middle.
Latex in the veins allow the 2 halves to hang apart on invisible threads.
