Lilacs are starting to bloom and should provide some lovely fragrance on Lilac Sunday. Not all lilacs are equally fragrant though; read Jack Alexander’s description of a nose-powered study of the lilac collection. Seen here is Syringa vulgaris ‘Prince Notger’ (accession 3001-1*A), one of many fragrant cultivars of common lilac.
