Which plant is known as Jack Frost Heartleaf Brunnera?

The plant known as Jack Frost Heartleaf Brunnera is correctly identified as Brunnera macrophylla 'Jack Frost'. This variety is particularly celebrated for its captivating foliage, featuring silvery leaves with contrasting green veins. The plant is also known for its beautiful blue flowers that resemble those of forget-me-nots.

Brunnera macrophylla, commonly referred to as Siberian Bugloss or False Forget-Me-Not, thrives in shady areas and is often used in garden designs for its ability to add texture and color to low-light conditions. The cultivar 'Jack Frost' was specifically selected for its unique leaf coloring and variegation, setting it apart from other varieties in the same genus.

While the other options like Astilbe, Coreopsis, and Anemone are all valuable and popular plants in their own right, they do not correspond to the Jack Frost designation. Astilbe is known for its feathery flower clusters, Coreopsis for its bright yellow flowers, and Anemone for its various types and seasonal interests. Each has its place in horticulture, but none match the characteristics of Brunnera macrophylla 'Jack Frost'.
