One of Olga's latest releases, 'All That Jazz' displays large heart-shaped leaves with a clean, creamy-yellow margin. It forms a majestic clump with a stately, spreading form, suitable for underplanting with ground covers. White flowers top the clump in midsummer. A sister seedling of 'Mardi Gras' ('Christmas Tree Gala' and H. montana 'Praeflorens').
