Few species in the small Amsonia genus have exceptional ornamental value. Amsonia tabernaemontana often called eastern blue star or simply blue star, is one of the most beautiful.

With its thick clusters of light blue spring blooms and golden autumn leaves, it is a native perennial that needs to be featured in more northern garden designs. 

Native to the Midwest, the eastern blue star is a hardy herbaceous perennial. A thick, shrubby plant with a maximum length and width of 312 feet and 2 feet is formed when many single stems emerge. It has lance-shaped green leaves whorled along long stems that end in dense panicles of beautiful 34-inch blue star flowers that put on a show from late spring to early summer.

After blooming, narrow bean-like pods are common and may provide extra late-season appeal. Eastern blue star’s deep brown principal veins contrast wonderfully with the gold willow like leaves when the temperature cools in the autumn.

What does the Blue Star flower symbolize?

The common name “blue star” refers to star-shaped flowers.

The blue star flower symbolizes resilience, strength, a force of will, and endurance, which are all represented by Amsonia blossoms. 

All in all, the blue star flower symbolic meanings are:

  • resilience
  • strength
  • the power of will
  • endurance
