Heuchera Primo 'Black Pearl' easily rivals the classic 'Obsidian'. It forms an incredibly dense mound of shiny, jet-black leaves with scalloped, ruffled edges. Each of the large leaves has a rosy purple underside which you can glimpse due to the intense ruffling. 'Black Pearl' will maintain its intense colour even in full sun. White flowers with pink calyxes appear in mid-summer.
