This Alchemilla 'Lady’s Mantel' and Heuchera 'Wildberry' in the backyard Office Box. (BYOB03a, BYOB01)

"The intense purple color of these leaves are second to none! Compared to 'Blackberry Ice', the foliage is larger, a richer hue, and holds onto its purple color for much of the season. Large, scalloped, incredibly glossy leaves are a bold shade of purple. Charcoal veins accent the leaf color that make the leaves really pop. Dark stems hold rosy pink calyxes and white flowers." -https://www.waltersgardens.com/variety.php?ID=HEUWI
