Don’t let the name blazing star intimidate you. These flowers are easy and fun additions to anyone’s garden. They need little to no maintenance and will cause you no trouble! Follow our guide to learn everything you need to know about the Liatris flower.

About the Blazing Star

The blazing star belongs to a large plant family. It comes from the Asteraceae family, which is just a fancy way of describing its flowers. The plant blooms clusters of small flowers. If you are looking to attract pollinators like bees and birds to your garden, plants in this family are the way to do so! Bees especially love these purple flowers.

The Liatris spicata is native to the eastern and southern United States. It blooms throughout the summer and into the fall. They feature fuzzy flowers that come in a range of colors depending on which variety you choose.

How to Grow the Blazing Star

If you are growing the blazing star from scratch, it’s important to note that they do not grow from a bulb. They sprout from corms, which are similar to bulbs but have a more wood-like texture. If you are looking to grow big and impressive purple flowers, you’ll want to plant the biggest corm you can find. If they are three inches or more in diameter, you will get large flowers.

When placing your corms in the ground, make sure they are spaced out.  Each corm will need to be at least 12 inches apart. You’ll want to be sure to place them two to four inches deep in the soil.

You can also grow the Liatris spicata from seed. What you’ll need to do is wait a month for germination. Cold and moist weather speeds the germination process up. Early spring is the ideal time to try to grow these beautiful plants from seeds. It is important to note that if you are growing these flowers from seeds, they will not bloom until the second year. Growing the blazing star plant from seeds is only beneficial if you want to cover a lot of ground with the flowers. Otherwise, growing from corms is an easier way to do it. Propagating your blazing star plants can help you cover more ground, but it will be a longer process.

Propagating Your Blazing Star Plant

The blazing star plant is easy to propagate. You can propagate your plant after the stems have died in the wintertime. Once you have dead stems, you will notice small corms coming from the large corm. These are known as cormels. You’ll want to pick them off the stem and store them in a cool space until springtime. Then you can plant them in your garden. It’s that simple to propagate your Liatris spicata!

Blazing Star Varieties

There are over 40 types of blazing star plants in existence! Out of all of those, there are three that are most commonly grown in gardens. These are the spicata, aspera, and pycostachya types. They come in a range of colors. The most popular varieties include the dotted blazing star which is a purple flower and floristan white which blooms a white flower. Other popular varieties are the kobold which grows a rose colored flower and the September glory, another purple bloom. The Heller’s blazing star is considered a threatened species as explained by this research by the University of North Carolina.

Caring For Your Blazing Star

Watering and Fertilizing Your Blazing Star Plant

After you first place your corms in the soil, you’ll want to water them well. Water them generously early on for ideal growth. After that, you’ll focus your watering on the climate. During the hottest months of the year, you’ll soak them in about an inch of water once a week. These plants can see fungal infections, so using or installing an irrigation system is ideal. If that is out of your budget or unreasonable for your garden, you can keep your blazing star happy yourself. Just make sure you are watering them at the base of the plant.

You will water them the most during their first year in your garden. That is when they need the most attention. However, these plants become very low maintenance after this initial year. They can be drought tolerant and can handle dry soil. As long as you water them thoroughly for about a year, you don’t need to worry about how much you water them from there.

Another low maintenance aspect of the blazing star plant is the amount of feeding it requires. You likely will not have to fertilize your flower. If you think the plant is not getting enough nutrients from its soil alone; you can use a balanced flower fertilizer once a year. The best time of year to fertilize your blazing star plant is spring as it begins to bloom.

Pruning Your Blazing Star Plant

Pruning is a helpful tool to keep your plants happily growing. If you prune your plant after its growing season, it will help produce more flowers the following spring. You’ll want to prune your plant in the fall time. Make sure the flower has stopped blooming and all blossoming spikes have gone away. Pruning your plant prematurely can impact growth.


As with water and fertilizer, the blazing star plant is also low maintenance with soil. Just about any type of soil will be fine for this plant. The only requirement is that it drains well. Other than that, you don’t have to sweat the type of soil you use to plant your corms.
