'Black & Bloom' is a new cultivar developed by Ball FloraPlant that seems to have limited release in the summer of 2015, but should be more widely released in 2016. It is supposed to be an improvement over 'Black & Blue' in vigor, form, and floriferousness. Apparently, 'Black & Blue' has lost much of its original vigor after many years of tissue culture. Like 'Black & Blue', 'Black & Bloom' has deep blue flowers held in a blackish calyx. It is currently rated as hardy in USDA Zones 8-10.

It is just starting to bloom for me, but I have already witnessed it being used by the hummingbirds.
