Brunnera 'Jack Frost' Characteristics
The unique foliage of Brunnera 'Jack Fost' adds character to areas that may be one-dimensional. The variegated foliage helps it stand out from other small perennials and groundcovers that are green and nonflowering.
Standing up to 18" above the foliage are the flower stalks. The somewhat star-shaped, pale blue flowers complement the dark greens and whites of the leaves well.
Well-suited to the Pittsburgh climate, Brunnera prefer cooler soils with consistent moisture. The soils should be relatively fertile. If left in the direct sun, especially during the hottest summer months, the leaves may scorch. These clump-forming perennials may become groundcovers if left to spread by their underground shoots.
The large, heart-shaped leaves can fill bares spots or create borders around garden edges. 'Jack Frost' can fill areas beneath trees and shrubs or along river and pond banks. They can also be left to spread when planted in woodland areas. Occasionally, 'Jack Frost' are used in outdoor containers along with other flowering plants.
