Brunnera Macrophylla, Viper's Bugloss, Alkanet, Sea Heart

Brunnera is a clump forming perennial for parts of the garden where moist shade prevents other ground
covers from thriving. Not only is it low-maintenance, but it has long-lasting sprays of flowers, is rabbit
Brunnera Silver Heart
and deer resistant.

The most common name used for these plants is bugloss, from two Greek words: ox and tongue
because the rough leaves looked and felt like ox tongues to the person who named it. The new hybrids
look more like silver and green or cream and green hearts than ox tongues, but still have lovely clusters
of flowers.

The old medicinal variety, Echium vulgare or Viper’s Bugloss, is sometimes found in seed catalogs listed
as Blueweed (see Richter’s Herbs To see several other Echium varieties, look no
further than Annie’s Annuals at

Another common variety, Lycopsis arvenis, is called Small Bugloss. It has waxy, toothed leaves and its
flowers are wheel shaped.

Historically, Viper's Bugloss was used to expel poisons and venom, and to cure the bites of a viper,
hence its name. The snake head appearance of the seeds led people to think it was a cure for serpent
bites. Echis is the word for viper and Echium stems from that history.

Brunnera Sea Heart
Water steeped with Bugloss root was taken for a trembling heart, swooning, and sadness caused by
passions and melancholy. Water steeped with the leaves was made into a cordial used for headaches
and nerves. The seeds were steeped in wine to comfort the heart.

The Brunnera used in shade gardens is in the same plant genus. Be sure to look for Brunnera when
shopping for the seeds or plants unless you specifically want the medicinal.

Brunneras are cold hardy from zone 3 to 9 and appreciate quite a bit of shade in our zone 7 since the
leaves burn in too much sun. Most varieties mature at a maximum of 18-inches tall when in bloom and
are a ground hugging clump the rest of the time.

The generic Brunnera macrophylla is a tough plant with solid green leaves. The varieties available for
purchase have other leaf colors. Companion plants with similar cultural requirements include Hostas,
Hellebore, Lamium, Japanese Painted Ferns and Bleeding Heart.
