‘Royal Velvet’ is a 3 ft tall specimen, erect with an open habit, with silvery-grey foliage. Flower stems are long, up to 16 inches, and very upright. The flower spikes can be up to 5 inches long. Flower petals (corollas) are bright violet-blue, and calyces are dark violet, with a bit of green at the base. This selection blooms in mid-summer, with great flowers for drying and crafting. It is not a good selection for oil. It is a beautiful specimen plant for large hedges. It was first grown at Norfolk Lavender in England after the Second World War.
