Cultural Significance

Prairie Blazing Star is one of the quintessential symbols of the North American tallgrass prairie -- a landscape that once covered over 170 million acres of the continent and has since been reduced to less than 1%. Its striking, top-down blooming sequence and brilliant purple color made it a landmark plant that prairie travelers and naturalists noted with awe. In many Indigenous traditions, Liatris species were used medicinally, particularly for throat ailments and as a general tonic, and were associated with vitality and healing energy. In the modern language of flowers, blazing star represents enthusiasm and bliss, reflecting its exuberant summer presence and its role as one of the most generous providers of nectar for the monarch butterfly during its southward migration.

Physical Characteristics

Flower Size: Individual flower heads 0.25-0.5 inch (6-12 mm); flower spike 6-24 inches long (15-60 cm)
Plant Size: 2-5 feet tall (60-150 cm), 1-2 feet wide (30-60 cm); strictly upright, clump-forming from a corm
Flower Shape: Dense, cylindrical, cattail-like spike of many small, feathery, disc-flower-only heads crowded along the upper stem; flowers open in sequence from the top down; long, pointed purplish-tipped bracts distinguish it from other Liatris species

Natural Habitat

Native to: Central and southeastern United States (Wisconsin and South Dakota south through Iowa, Illinois, Missouri, Kansas, Nebraska, Oklahoma, Texas, Louisiana, Mississippi, and Ohio), Scattered populations east to New York and Pennsylvania
Habitat: Moist to dry tallgrass and mixed-grass prairies, wet-mesic prairies, open fields, meadows, roadsides; one of the few Liatris species tolerant of moist or even clay soils
Climate: Temperate, Continental, Humid

Growing Guide

Sunlight

Full sun is essential for straight, upright stems; partial shade causes stem twisting and leaning

Water

Medium moisture; one of the most moisture-tolerant Liatris species and able to grow in moist clay soils; also drought tolerant once established through its deep corm

Soil

Moist to well-drained, Clay-tolerant, Sandy loam, Rocky, Poor to average fertility

Expert Growing Tips

1

Plant corms 3-4 inches deep and 12-18 inches apart in full sun in spring or fall

2

Mature corms can be divided every 2-3 years in spring to propagate new plants

3

Plant in full sun to prevent stem twisting -- this is the most common cultivation issue

4

Leave seed heads standing through winter; goldfinches feed on the seeds and the structure adds winter interest

5

Pairs beautifully with purple coneflower (Echinacea purpurea), wild bergamot (Monarda fistulosa), and prairie dropseed (Sporobolus heterolepis)

Frequently Asked Questions about the Prairie Blazing Star

What does prairie blazing star symbolize?

Prairie blazing star symbolizes bliss, ambition, and vitality. Its tall, exuberant spikes of summer purple have made it an emblem of enthusiasm and bold joy, and its generous provision of nectar for monarchs and pollinators links it to themes of generosity and ecological abundance.

Why does blazing star bloom from the top down?

Unlike most flowers that bloom from the bottom up, Liatris species bloom from the top of the spike downward. This is thought to be an evolutionary adaptation that benefits pollinators -- insects can work their way up from the older, more developed flowers at the bottom to the fresh, newly opened flowers at the top, improving pollination efficiency.

Is prairie blazing star good for monarchs and butterflies?

Yes -- prairie blazing star is one of the most important nectar sources for monarch butterflies during their late-summer southward migration. It also attracts many other butterfly species, native bees, bumblebees, and hummingbirds, making it a top choice for pollinator gardens.

How tall does prairie blazing star grow?

Prairie blazing star typically grows 2-4 feet tall, though in ideal moist conditions it can reach up to 5 feet. It is one of the taller Liatris species, making it an excellent back-of-border plant. Individual mature plants can produce up to 42 flower spikes, though 10 or so is more typical.

How do you grow prairie blazing star from corms?

Plant corms 3-4 inches deep in full sun with average, moist to well-drained soil in spring or fall. Unlike most Liatris, this species tolerates clay and moist conditions well. Ensure full sun to keep stems straight. Corms can be divided every 2-3 years to propagate new plants.
