Looking Glass Siberian Bugloss
Light blue forget-me-not-like flowers with yellow centers appear in early April and lasted four weeks for some of our evaluators. Others noted plants never bloomed or bloomed sporadically.
Foliage interest – color/texture
Unique feature of this medium textured plant is the silver heart-shaped foliage with fine green veins.
Habit and growth rate observations
On sites where Looking Glass performed best, mounds were 12 inches tall and 18 inches wide, with flowers floating 6 inches above the basal foliage. Plants that struggled and bloomed sparsely or not at all were 10 inches tall and 8 inches wide.
Site preference – soil & light
Plants did best in dry shade with some morning sun. Good soil drainage is essential.
Successes and possible drawbacks – how to overcome them
Plant Looking Glass with good air circulation and water only as needed in the morning hours. Looking Glass competed well with maple roots, but two hours of exposure to high sun caused leaf edges to scorch. Some evaluators found that a top dressing of compost in spring and fall was beneficial. In all but one site, the foliage was affected by black leaf spot during the hot and humid days of summer.
Notes from growers/retailers
Looking Glass looks good in a container but has a short retail shelf life. Grow Looking Glass on the dry side and monitor salts carefully. Keep fertilization low. Does not like heat and growth rate is slow.

Parting SHOT – the overall evaluation results were Fair**
Even though the mostly silver leaves are very striking, the overall plant performance is not as dependable as Brunnera macrophylla ‘Jack Frost’ or Brunnera macrophylla.
