The Sweet Mockorange is native to southeast Europe and Asia Minor. It is an old-fashioned shrub that was used a good amount in the Midwest, Mid-Atlantic, and Northeast USA in many landscapes from the late 1800's into the 1960's, and many are still alive. It grows to be a large, rounded shrub with stiff ascending branches that arch with age, and it is rather twiggy and gets straggly. It is noted as having very sweetly fragrant flowers in late May into early June for about 10 days or so. It does not develop fall colour. It is very reliable; not bothered by anything serious. Very few conventional nurseries offer this species now. The trend has been to have smaller Mockoranges that bear double flowers.
