Dwarf Barbados Cherry 'Nana' (Malpighia punicifolia)
Source tree from Top Tropicals, Feb 2017
This is a cool little shrub. I love the dense foliage. I have it planted right next to a rosemary, and it takes full sun with western exposure just fine. It has not fruited for me yet, but it is so ornamental that I am cutting it a lot of slack :)
