Lavendula angustifolia 'Munstead' is a compact Lavender with vivid blue-purple flowers. 

 Like all Lavenders 'Munstead' attracts bees in profusion. For maximum bees it's worth planting one of the Lavandin cultivars i.e. Lavendula x intermedia which is the hybrid of L. angustifola and L. latifolia. They are the most aromatic and bees mob them.
