Descriptive Features: Named the 2025 Proven Winners National Perennial of the Year, this dramatic selection can best be described as a giant, souped-up version of the classic 'Jack Frost.' Huge, oversized heart-shaped leaves — a full 9 to 10 inches across — overlap dramatically at the base, creating an almost perfectly circular silhouette from a distance. A heavy silver overlay covers the foliage, accented by a vivid, wide, dark green veining pattern for striking contrast. In mid to late spring, dainty sprays of baby-blue, forget-me-not-like flowers rise above the emerging foliage on tall scapes, adding delicate color before the bold leaves take over for the season. Its slightly fuzzy leaf texture makes it naturally unappealing to deer. Low-maintenance and easy to grow, thriving in average to fertile, consistently moist soil in part to full shade. An outstanding choice as a specimen or focal point, or planted en masse for maximum visual impact in woodland gardens, shaded borders, or container plantings.
