The common name of Philadelphus is Mock Orange and the reason is that this plant smells wonderfully of orange blossom.
Mock Orange has really strongly scented even from quite some distance away, and like many white flowering plants, the scent is even stronger in the evening. Philadelphus ‘Belle Etoile’ makes a wonderful informal billowing hedge as seen in our photograph. It is profuse flowering, with large white single flowers with purple centres, in June and July and often flowers for many weeks. The arching branches are covered in mid-green foliage which is deciduous.
