Syringa komarowii subsp. reflexa - pendulous lilac
Pendulous lilac has, as the common name suggests, distinctly pendulous cylindrical clusters of flowers, as much as 20 cms (8 inches) long. In contrast, when the seed pods form they curve upwards, which is the basis of the Latin ‘reflexa’. Flower buds are usually carmine, but on opening the flowers gradually fade to almost white.
