Mock Orange is a deciduous shrub that is perhaps not as popular as it once was. Possibly its potential to make a very large shrub – in excess of 20 feet high and equally as wide – sometimes puts people off having a Philadelphus in their garden. However, small varieties are readily available, and it’s a plant that is well worth having. This popular variety which flowers in June to July is Philadelphus ‘Belle Etoile’, and is one of the more compact ones, growing maybe to only 2M in height with fragrant flowers.
