Brunnera macrophylla Jack Frost (Siberian Bugloss)
Although its clouds of bright blue flowers add cool and striking color to the landscape in spring, ‘Jack Frost’ is mostly valued for its beautiful foliage which creates a lush carpet of heart-shaped silver leaves
Grown for its particularly attractive foliage, award-winner Brunnera macrophilla 'Jack Frost' features large, heart-shaped silver leaves edged and veined with green, and clouds of tiny, pale blue, airy flowers in spring. Resembling hostas, the basal foliage forms a dense and lush mound, which remains attractive throughout the entire growing season.
- Won the prestigious Award of Garden Merit by the Royal Horticultural Society for its noteworthy qualities
- Clump-forming, this deciduous perennial slowly spreads by creeping rhizomes and grows up to 12-18 in. tall and wide (30-45 cm).
- Fairly resilient to most pests and diseases, deer and rabbit resistant, and is easy to care for.
- A part shade or full shade lover, it thrives in organically rich, moist, and well-drained soils. Dry soils are to be avoided! A cool site in partial shade or shade is preferred.
- A remarkably low-maintenance plant, this excellent performer may be used as a specimen plant or massed as a ground cover. Perfect for beds and borders, banks and slopes, or underplanting shrubs and roses.
- Propagate by division in early spring or take root cuttings in winter
- Deadhead after flowering if self-seeding is not desired.
- Pruning is essential for good looks and health. Promptly remove unsightly foliage, whether damaged from sun, drought, or pests.
