Lavandula angustifolia Melissa Lilac ('Dow4') (PBR), lavender. Stunning, large, violet-coloured, fragrant flower spikes appear in summer above slender, aromatic, silvery-grey leaves. This is a lovely lavender for edging paths and borders; the aromatic foliage perfumes the air if you brush against it. It also works well in a gravel garden, or clipped into a formal sphere for a contemporary look. The flower-spikes are highly attractive to bees and other beneficial insects.
