Philadelphus 'Innocence' is a deciduous shrub that develops a loose but structured framework of woody stems. Its leaves emerge green with irregular pale markings, giving the plant visual interest beyond its flowering period. White flowers appear seasonally along the stems, after which the shrub continues in leaf until autumn, when foliage is shed. Growth is steady rather than aggressive, and the plant responds well to routine pruning once flowering has finished. This variety is suited to garden settings where both foliage pattern and seasonal bloom are valued without the need for constant maintenance.
