[Wikipedia] Name Info, Range: Despite the common name, rock sea-lavender is not related to the lavenders or to rosemary but is a perennial herb with small violet-blue flowers with five petals in clusters.[2]
Eight rock sea-lavenders are endemic to Britain and Guernsey[3] and the taxonomy was reviewed in 1986 to include a range of subspecies. (link added by Mary Ann Machi)
