Botanical Name: Brunnera macrophylla 'Jack Frost' BRUN-er-ah mak-roe-FIL-lah Genus: Brunnera

Noteworthy characteristics: Highly valued for striking silver variegated foliage. Powder blue flowers hover over the plant in spring.
Care: Remove ragged foliage in late fall and snip off the spent flower stalks in early summer to keep this plant looking its best.
Propagation: Sow seeds in container in spring. B. macrophylla should be divided in winter.
Problems: None serious, but watch out for too much sun or hot sites.
