There are four identical beds edged with lavender with Box cubes at the corners, they are planted with Perovskia. The front 2 beds are under-planted with Tulipa White Dream and Allium. There is no summer irrigation.
In September the lavender was cut back (this is too late).
The lavender grows so much I am considering changing it to box or myrtle. Also as I grow older I love the formality of the pruned lavender almost more than when its flowering, though of course I do love the bees and butterflies that are attracted to it, not to mention the wonderful perfume.
