Every summer I find my garden looking tired and dull, probably because of the low moisture and high heat conditions. After the vigorous growth of my plants during spring, grasses started to go dormant and new foliage breaks its development, keeping the plants from blooming. This has largely affected the appearance of my garden.

That is why when I found out that there is a flower called Blazing Star that can add beautiful color and dramatic form, and create plenty of ornamental designs to one’s summer garden, I was immediately drawn to it. Moreover, the easy planting method, care, and maintenance are a bonus to consider this plant in a garden.

Blazing Star

Liatris Spicata, also known as Blazing Star, is probably one of the easiest and most versatile plants to grow in a garden. It grows from knolls of thin, grass-like leaves measuring about 1- to 5 feet tall. Liatris flowers have tall, spikey, and fuzzy purple blossoms, while some vary from white to rose colors. Its foliage will shine green throughout the season before changing bronze in fall.

Blazing Star Facts

Different varieties of blazing star are to be found in different regions especially in United States. It varies in color and height depending on the soil and weather conditions of its native setting. Although blazing star varieties can be quite similar to each other, the list below will tackle its similarities and especially its uniqueness to each other.

Dotted Blazing Star (Liatris punctata)

Dotted blazing star has round shaped flowers with colors of pink from the bottom to purple on the head. Its head measures about ½ to ¾ inch long packed in clusters of up to 10 inches long. The head is also comprised of three to eight disk flowers, which are shaped like stars with a long curve dividing the center.

The leaves are very narrow that make it look like some sort of grass about 4 inches long and ¼ inch wide. The leaves are also full of short white hair all over the skin like dots of resin. That is why it’s called dotted blazing star.

Floristan White (Liatris spicata)

Floristan white is a kind of blazing star that is unlike common ones. It has two-foot white spike blossoms. Each of its flowers is packed with blossoms rich with nectar, which will surely attract butterflies. Each Floristan white can produce multiple flower spikes that make a strong upward spirit in a garden.

Caring for this plant is easy for it is considered low-maintenance. It may extend up to 24 - 48 inches tall and widen up to 12 – 18 inches when matured.

Usually found in Ontario and Quebec in Canada, Massachusetts, Florida, Wisconsin, and Louisiana in the US, this species wants moist sandflats and sunny sites. It is smaller in size, ranging a height from 18 to 30 inches tall, yet can produce several sturdy stems. Another fun fact is the name Kobold is derived from the word Goblin because of the big-headed flowers it produces.

Rough Blazing Star (Liatris aspera)

Rough blazing star is planted best in areas with dry to medium moist soil condition. That’s why it is often associated with jack pine woodland or oak. It is a late bloomer as it takes a while to grow from seeds, but it can grow flowers in its second or third year.

Similar to common blazing stars’ characteristics, rough blazing star has vivid violet color flower standing in a stalk of 2-4 feet tall, and narrowed basal leaves extending up to 6 inches from the base.

September Glory (Liatris scariosa)

Stalks with reddish purple flowers is a trademark of September Glory. Its long lasting color makes it a great choice even during summer or even frost season. Fine and long spike grass-like leaves become longer in summer, rising to about 45 centimeters from its base. This type is considered to be the most productive and efficient one for it can withstand heat, cold, and even drought.

How to Grow Blazing Star

How to Grow Blazing Star

It may be surprising but planting and taking care of Liatris plants is definitely easy, plus it gives many benefits and uses in the garden. Although every other variety of blazing star may prefer different soil conditions, you can actually start planting it anywhere in your garden – in beds, containers or borders.


Blazing star doesn’t require a specific type of soil. This means you can grow it on soil of any fertility level, though it prefers slight acid or neutral soil pH level. Ensure quick drainage to prevent the corms from rotting.


Although Liatris plants commonly want full sun, it does not mean they cannot tolerate a little shade. It can tolerate both, but to ensure best and healthy results, always place your blazing star on where the sun shines the most.

Temperature & Humidity

Blazing star can withstand different seasons - from major heat to major cold temperatures. It can withstand drought, yet it can also tolerate the cold. However, it is best to give it more pampering before the winter starts, and make sure the soil will not get any wetter to keep roots from rotting. It is a must, especially in areas with fast-changing seasons.


Watering does not require much work. Just provide adequate water, especially to newly planted seeds and corns as needed for the first weeks from germination period. After the first few weeks, it will no longer require that much water. In fact, just give the blazing star little water and allow drying of soil before watering again. Before the winter season starts, make sure the soil is near to drying as too much of water in the soil can rot the corms and the roots.


There is also no need to secure it from getting infected by pests because blazing star plants are proven to be pest resistant. Thus, fertilizer is just optional. It can be added to the hole during planting time for a good start. However, you may experience powdery mild dew and leaf spots in some seasons, but it isn’t a big concern. To avoid deficiencies, you may want to consider avoiding lower areas exposed to water because too much wet soil can make the root rot easily.

If you want to push through with the fertilizing method, blazing star can be planted on a mixture of lime or horn meal and compost. However, during the August period, it should not receive fertilizers anymore.

Here is a quick and short guide for fertilizing your Liatris:

a. In a bed, slightly rake the compost for two weeks
b. During Spring: if not fertilized with compost, it may get a complete fertilizer during this season
c. Flower: You may also try giving the flowers some flower fertilizer once a year


The word pruning may sound tedious but in the case of blazing stars, the foliage and stems can be managed and cleaned-up anytime it’s already dry, and shades of brown, bronze and orange are slowly showing up on the stems. However, for me, I prefer to let it sit for a while during the fall and winter seasons, even until spring to add a nice touch of color to the garden. In the early days of spring, you can make use of the vegetative debris and other side dress clumps by creating an organic compost, manure, or humus.


Do you want good news? Mulching in blazing stars is not really necessary. But if you want to do mulching, you may start working before the ground freezes during the winter. Simply apply a light and airy mulch of maybe boughs of pine and you’re good to go. I do recommend mulching as it has a lot of benefits, especially when it’s done in a proper and organic way.

Mulching can provide soil microbes such as mycorrhizae, earthworms and nematode. These microbes help in improving the soil condition, thus letting the root to penetrate deeper into the soil. It also helps reduce moisture in soil and prevent the weeds from growing near your baby plants. Personally, I would recommend mulch of long leaf pine straw for it lasts longer in the garden compared to others. 


There are two ways of propagating blazing star – by division or by seed. You may try propagating by division during the spring season. You would need to dig up large clumps and divide them every three to four years to provide adequate spacing and avoid overcrowding.

For those who are not fond of outside or backyard gardening, there is no need to worry because liatris seeds can also be propagated indoors. The good thing about this is you can monitor the germination more when it is planted indoors. Germination usually takes from 20 to a maximum of 45 days if ever the seeds are exposed to cold and moist conditions. After germination, they can be sowed outdoors during fall or early winter, which can add to letter results.

In terms of planting and blooming season, blazing stars are usually planted in early spring, yet in some areas, they are also planted during fall. It grows from being a typical corn into a full-bloom flower in late summer. What is more amazing is the fact that waiting will not take long since blazing stars can attain full-grown size in the same year it was planted.
