'Blue Empire’ is big, blue, and beautiful! Its powdery grey-green foliage is the perfect skirting to present the long wands of stacked deep blue flowers. The flowers are bigger than others, making it a wonderful addition to the landscape or container garden as well as an excellent choice for cut flowers. Compact habit and late season blooms attracting pollinators from miles around.
Full sun, drought tolerant, deer resistant. Grows 3 feet tall and wide. Prune this compact woody shrub in late winter to encourage bushy new spring growth.
