Announcing the changing of the seasons and the coming of summer, Lilacs are ubiquitous both within gardens and as a wild flower. Their scented flowers are well-known to many with whorls of fragrant blossom sitting perfectly at nose- height. Symbolising first love, their fleeting bouquet can provoke a sense of nostalgia. Naomi Slade explores a wide range of different Lilacs, drawing our attention to the varying shades of pink, lavender, mauve, burgundy and of course, lilac, and also to white, blue and yellow varieties.
