Brunnera (Brunnera macrophylla) — also known as Siberian bugloss,”Jack frost,” brunnera heartleaf or variegated bugloss — is a ground cover plant that grows best in U.S. Department of Agriculture hardiness zones 3 to 8. Common in shade gardens is a perennial that can grow up to 24 inches wide and 18 inches tall. The plant produces blue flowers in summer and is best propagated in early spring.
Dig up overcrowded clumps of brunnera with trowel or a fork, being careful to not disturb the roots at the procedure. If you are currently working with only a small part of brunerra, a hand fork can get the job done as well. Brunnera is a perennial with an extensive root system, so you may need to separate one into clumps.
Shake off excess soil and find the most healthy origins for branch. Wash away excess soil if you cannot see the roots.
Discard diseased or weak areas of the plant.
Divide the wholesome roots into small sections. This can be accomplished by hand, but if the plant is demanding, use a knife to do this. Do teasing out the origins instead of pulling them apart, when the brunnera carve.
Replant your divisions in prepared containers with a soil thickness equal to that of the soil thickness of where the plant was originally planted. Brunnera does best in well-drained loam or sandy soil. Rather than trapping them collectively, be sure to spread the roots out once you plant. With the soil, there is not any demand for compost after replanting. Maintain the soil in with all the transplants moist but not overly wet.
