Mockorange

Mockorange has typically been a large, unruly shrub with dull, paper-thin leaves that appear ratty and tattered. This new, compact introduction from Proven Winners, 'Illuminati Arch' Philadelphus, has thick, handsome, rugged foliage that keeps its deep green colour all season long. Early summer brings cascades of double white flowers with the sweet, old-fashioned mock orange scent that everyone loves.
