Types of Blue Star Plants

There are several types of Blue Star plants, each with its own unique characteristics. Here are some of the most popular ones:

Amsonia hubrichtii

Also known as Arkansas blue star, this plant produces clusters of small blue flowers on long stems in late spring to early summer. Its narrow leaves turn a golden-yellow color in the fall, making it a great addition to any autumn garden.

Amsonia tabernaemontana

This variety is also known as blue star or eastern bluestar. It has larger flowers than Amsonia hubrichtii and blooms in late spring to early summer. Its leaves turn vibrant shades of yellow and orange in the fall.

Amsonia illustris

Also called Ozark blue star, this variety produces clusters of dark blue flowers on top of light green foliage in late spring to early summer. Its leaves turn yellow in the fall.

Choosing the Right Blue Star Plant

When choosing a Blue Star plant for your landscape, you should consider several factors. Here are some things to keep in mind:

Soil and Sunlight Requirements

Blue Star plants prefer well-drained soil and full sun to partial shade. Make sure you choose a spot in your garden that meets these requirements.

Bloom Time
