Philadelphus are tolerant of most soils in full sun or light shade. However, yellow-leaved Philadelphus coronarius ‘Aureus’ may need a little protection from strong sun.
Philadelphus dislike very heavy, permanently wet soils. By avoiding poor, dry soils or deep shade, plants will be more vigorous and floriferous.

You can clip over Philadelphus coronarius ‘Aureus’ immediately after the flowers have faded to encourage a fresh crop of bright golden-yellow leaves – older leaves turn to green in summer.
