(Coral Bells) Heuchera 'Tiramisu' PPAF is another new exotic heuchera from France that offers a rainbow of colors that change with the seasons. In the spring, the young leaves emerge bright yellow with brick red centers that radiate out through the veining of the leaf. By mid summer, the leaves lighten to a chartreuse coloring that is frosted in silver and topped with airy stems of creamy-white flowers. When autumn arrives, the brick red coloration returns and covers the entire leaf, except for a bright chartreuse margin that highlights the red color! Heuchera 'Tiramisu' also thrives in heat and humidity and is destined to become one of the best new perennials on the market!
