'Lavender Lassie'. Kordes, Germany, 1960. Though launched as a Floribunda, if pruned lightly this will grow into a tall, graceful, open shrub and is always in flower, its large and small trusses of soft lilac-pink flowers, sweetly scented, blending with many gentle colour essays. Good dark glossy foliage, disease-proof. 8 feet by 4 feet.
