Philadelphus coronarius 'Aureus'
Golden Mockorange, Mockorange
The ivory-white flowers of ‘Aureus,’ or golden mockorange, have a delicate orange-blossom scent that perfumes the air in late spring to summer. This large deciduous shrub, is descended from a native of southeastern Europe and Asia Minor. It covers its arching branches with white four-petalled flowers so profusely that it turns more white than green. The leaves are toothed and oval and they alternate on the branches, which are red-brown. The leaves emerge golden yellow in spring, turn bright yellow-green by summer, and remain that shade until they drop.
Grow ‘Aureus’ in full sun for best form and heaviest flowering. Shade causes plants to become leggy and sparse. This shrub tolerates almost any fertile, well-drained soil and a degree of drought. Plant it where passersby can appreciate its fragrance. Tall and dense when grown in full sun, it's suitable for screening and ideal for the back of mixed shrub borders. Prune the flowering stems back just after bloom, and remove old congested growth in early spring.
