Gardening on an angle – Nr. Shepton Mallet

This is a garden I designed in 2014, the client has planted it as a white garden and is finding out that white flowers are not always white.  So which are good whites?

Viola cornuta ‘Alba’
Choisya ternata ‘Alba’
Armeria maritima ‘Alba’
Digitalis purpurea ‘Alba’
Allium ‘Mount Everest’
Cosmos ‘Sonata
Pulmonaria ‘Sissinghurst White’
Hesperis matrionalis
Phlox
‘Mount Fuji’

to mention a few…
