Jackson & Perkins Brunnera Jack Frost

This plant thrives in partial shade, meaning it prefers dappled sunlight or morning sun with afternoon shade. Avoid planting it in full, harsh sun, as the delicate silvery leaves can scorch.

Yes, 'Jack Frost' is quite hardy and is suitable for USDA zones 3 through 7. It is a perennial, so it will go dormant in the winter and return in the spring.

It prefers rich, moist, and well-drained soil that is slightly acidic. If your soil is heavy clay or very sandy, amending it with organic matter like compost before planting will help it establish better.

Since 'Jack Frost' reaches a mature spread of about 18 inches, you should space them 18 to 24 inches apart. This allows enough room for the mound-shaped foliage to fill in without overcrowding.

It is considered a low-maintenance plant. You really only need to keep the soil consistently moist and perhaps trim back any tattered foliage in late summer or after the first frost to keep the garden looking tidy.

Because of its striking silver and green foliage, it looks excellent planted alongside other shade-loving staples like ferns, hostas, and heucheras. The blue flowers also provide a nice contrast to the deep greens of those companion plants.
