About this plant
Syringa x chinensis 'Lilac Sunday' is a deciduous lilac that flowers in spring, typically mid to late spring, with abundant, fragrant panicles of pale lavender-pink blooms. Flowers are produced not only at the branch tips but also from lateral buds along the stems, so the slender shoots can arch under the weight of bloom. Fresh green leaves and a fine-textured, willowy framework keep the plant looking light after flowering.
'Lilac Sunday' was selected at the Arnold Arboretum, associated with the Arboretum's annual Lilac Sunday celebration, and credited to Arboretum propagator Jack Alexander. It is grown for its dependable spring flowering, arching form, and good foliar health, fitting borders, hedges, and prominent planting spots near paths and patios.
