Capsicum annuum var. grindstaffum is a variety of Capsicum annuum most commonly known as the Black Pearl pepper. It is characterized by distinctive black leaves and fruit. It was developed by Arboretum Floral and Nursery Plants Research Unit scientists Rob Griesbach and John Stommel of the Agricultural Research Service’s Vegetable Laboratory. This pepper plant is notably similar to another strain, named the Black Hungarian, another designer pepper plant.  Though edible, it is considered an ornamental plant and even won an award for its beauty from All-Americas Selections in 2006. The Black Pearl has characteristic semi-gloss black to deep-purple leaves with peppers that are black and turn crimson when fully ripened.
