Jack of Diamonds Heartleaf Brunnera

‘Jack of Diamonds’ is a bold shade perennial with exceptionally large, overlapping silver leaves framed by broad green veins and sprays of baby-blue flowers in spring. Its broad mound makes a strong foliage accent in woodland borders, mass plantings, and containers. ## Foliage and flowers The [Walters Gardens cultivar profile](https://www.waltersgardens.com/variety.php?ID=BRUJD) describes 9–10 inch leaves that overlap at the base, creating a circular, escargot-like form, with baby-blue flowers from mid- to late spring. It lists plants at 14–16 inches tall and 28–32 inches wide, with USDA zones 3–8. The exact-cultivar [plant patent](https://www.hort.net/pedia/patent/grant/32752/) confirms the botanical identity and light-blue spring flowers, and notes thicker leaves that tolerate heat better than some related cultivars. ## Siting and care Use part to full shade, with consistent moisture and well-drained soil. Walters Gardens recommends moist conditions, especially in warmer regions; protect from hot afternoon sun and mulch to conserve moisture. The cultivar profile describes a compact, broad mound suited to shaded woodland borders and containers. ## Maintenance Remove spent flower stalks if desired and trim damaged foliage. Keep old leaves through winter where practical, then clear them as new growth emerges. Water during dry spells and avoid allowing the root zone to dry for extended periods.
