It thrives in shade but also likes morning sunshine as long as it is in consistently moist, rich, organic soil.[4][2] It does not tolerate dry conditions. It is often used in woodland gardens along streams of ponds and in naturalized areas as a specimen plant or clumped together as a border.[2] Clumps slowly spread by creeping rhizomes to form thick ground covers.

"Bugloss comes from Greek meaning ox tongue in probably reference to the roughness and shape of the leaves."[2] It is a herbaceous perennial that grows in a Zone 3 to 8.[2] In 2012 Brunnera macrophylla 'Jack Frost' was named perennial plant of the year by the Perennial Plant Association (PPA).[4] Based on the (USDA) Hardiness zone it is hardy in zones 3 to 8.[5]
