Know before you buy

This variety is hardy in USDA zones 5 through 9. As a deciduous shrub, it will lose its leaves in the winter and go dormant, returning with new growth in the spring.
For the best flower production, plant it in a location that receives full sun. While it can tolerate partial shade, you will see the most vibrant deep blue to violet blooms when it gets at least six to eight hours of direct sunlight daily.
Yes, it is an excellent addition to pollinator-friendly spaces. The late-season blooms are highly attractive to bees and butterflies, providing a vital nectar source when many other plants have finished flowering.
