Bred by Spitzbergen Willemsen and introduced into the US by Plants Nouveau.
'Silver Heart' Heartleaf Brunnera blooms in April and May, with cobalt blue flowers held over stunning silver and green heart-shaped leaves.

As many of you are already aware, the threat of Boxwood Blight is increasing in our area. At PRN, we are taking additional steps to provide healthy Boxwoods. First, we only source from growers who can provide Boxwood Compliance Certificates. Additionally, we are limiting access to our Boxwoods at the nursery. This is being done to reduce the risk of spreading the disease to healthy plants. Boxwood Blight is often transmitted through spores carried on shoes and clothing, and resistant but healthy Boxwoods have been shown to carry the disease as well. Customers will be able to view and order Boxwoods from PRN but they will be a “PRN Pull Only”. These extra precautions will keep PRN clean from Boxwood Blight so you can feel reassured that you are purchasing healthy, disease free Boxwoods which will thrive at your job site.
'Little Missy' Little Leaf Boxwood is an excellent substitute for Buxus 'Justin Brouwers' is areas where Boxwood Blight is increasingly a problem. The Buxus microphylla cultivars are much more resistant to the effects of the blight, and 'Little Missy', with it's compact mounding habit and diminutive size works well where really small Boxwoods are needed. The leaves are lustrous dark green and tolerate sun well. Buxus 'Little Missy' does well with trimming, so it can be used to make knot gardens and short formal hedges.

After years of observation it was named and released by the Arnold Arboretum because of its proven excellence. Slow growing and compact, it forms an excellent low maintenance shrub for shady locations.
