Lilac Sensation A much sought-after lilac with bi-coloured flowers, Syringa vulgaris Sensation is a tall, deciduous shrub with an upright, bushy, relatively loose habit and mid- to deep green heart-shaped leaves. In May and June, the shrub bears big trusses of reddish-purple flowers with white margins to the petals; they have a strong, delicious, lilac fragrance which carries on the air. This plant appreciates a mulch in early spring, but is otherwise very easy to grow; it thrives on chalk and dislikes very acid soils. Lilac Sensation holds the RHS Award of Garden Merit.
