An old fashioned double flowering lilac, Syringa vulgaris 'Katherine Havemeyer' is an upright deciduous shrub that will take on a spreading habit as the plant matures. Can tolerate hotter conditions than most lilacs.
Dense clustered panicles of fragrant, lavender-purple flowers fade to lilac-pink shades as they mature. May grow to 2-3m but can be kept more compact with pruning. Holds the Royal Horticultural Society's Award of Garden Merit for its reliable performance.
