Amsonia ‘Blue Ice’

Amsonia

<i>Amsonia</i> x ‘Blue Ice’

Springing forth in a seedling block of Amsonia tabernaemontana at Sunny Border Nursery, this energetic compact perennial has an unresolved lineage, with some speculating that either Amsonia montana or Amsonia orientalis may be a parent. What’s for certain is the fact that its flowers are the bluest, most vibrant and longest blooming ones amongst the genus. The pyramidal-shaped terminal clusters of navy-colored buds and starry lavender-blue blooms garnish a refined dense mound clothed in narrow, willow-like dark green leaves. ‘Blue Ice’s easily maintained habit beams brilliant yellow fall color, looks its best when massed and makes a spiffy deer-proof addition to rock work, borders or woodland peripheries.

Blooms May–June

Size: 12" – 18" high x 2' 0" wide.

Hardy to zone 4.

Our featured plant: Cercidiphyllum japonicum

Cercidiphyllum japonicum: A tree brimming with elegance....

An inhabitant of China and Japan, Cercidiphyllum japonicum usually grows as a refined multitrunked tree with a pyramidal to rounded canopy. Cloaking gracefully structured branches, the lovely somewhat heart-shaped deciduous leaves unfurl in bronzy purple tones, and later exhibit medium bluish green hues for summer. The foliar grand finale includes brilliant yellow, apricot, orange or mauve colors plus a sweet strawberry-like scent that wafts some 15 feet or further on sunny, warm fall afternoons. This easy-care tree prefers adequate moisture as well as some protection from hot scorching sun and drying winds.

Autumnal Allure...

One of the greatest joys of gardening is witnessing the changes that occur in our landscapes throughout the year, and many deciduous woody plants pretty much top the list for affording dynamic seasonal transformations, especially in autumn. Most of the trees and shrubs featured in this newsletter are renowned for both their handsome habits and prismatic fall displays. We’ve also included a few of our favorite perennials that lend late season floral or foliar intrigue.

All of us Digging Dog plant wranglers wish you Happy Digging!
