Liatris spicata 'ALBA' blazing star, gayfeather

Liatris

The genus Liatris is one of the quiet treasures of the North American prairies, a group of roughly forty to forty‑three species that evolved exclusively within the United States, Canada and, marginally, the Bahamas. It was first described botanically by Thomas Walter (1740–1789) in 1788, although the name Liatris became firmly established only later as a nomen conservandum, since several competing names circulated in early botanical literature. Modern taxonomy clearly separates it from the related genera Carphephorus and Garberia, despite certain shared morphological traits – a boundary that remained controversial for a long time until molecular studies finally resolved it. Liatris is a genus of plants that learned to live with fire, wind and seasonal flooding, and its upright flower spikes are now among the most distinctive symbols of the American prairie flora.

Carl Ludwig Willdenow (1765–1812) described Liatris spicata in 1803, and since then it has become one of the best‑known prairie perennials, largely because, unlike most other species of Liatris, it thrives in wetter soils and along marshy margins. Its natural range stretches from New York State down to Florida and westwards to Louisiana, growing in seasonally wet meadows, tall‑grass communities and the fringes of marshes – places that turn into hot, humming chambers of insect life during summer. In such habitats it becomes one of the most important nectar sources for butterflies, bees and hummingbirds, which is why American university gardens recommend it as a “late‑season nectar plant”. It reached European gardens in the early nineteenth century, when botanical institutions began cultivating it as an exotic prairie curiosity, and it gradually became a familiar perennial thanks to its reliability, long flowering season and ability to thrive even where other prairie species fail due to higher moisture levels.

Leafing through old prairie journals, I discover that blazing star was never just some purple bottle‑brush stuck in the grass, but a plant with a social life far richer than anything Marge Simpson ever enjoyed. Prairie warriors brewed a decoction from its roots to strengthen their voice before battle, because dust and smoke from the fires could turn even the bravest hero into a croaking wreck; blazing star gained a reputation as the plant that “cleans the breath” and “holds the voice”, which is perhaps the most poetic horticultural trait any perennial has ever had. Nineteenth‑century entomologists noticed something else: when it flowers, butterflies line up on its spikes like cars on a motorway – some species even lay their eggs exclusively on it, so you could say blazing star was a butterfly nursery long before ecological gardening made it fashionable. And then there is its relationship with fire: while most plants give up after a blaze, blazing star behaves as if it were its favourite sport. Prairie fire clears space and releases nutrients, so the plant shoots up with even greater enthusiasm – no wonder naturalists wrote, in full colour, that “after fire, the prairie rises like a purple Phoenix”. As if that weren’t enough, some communities used its dried roots as perfume for clothing. What do you think – could it compete with ripe quinces tucked into a wardrobe? 😊 In Illinois it was even planted along roadsides as landmarks for postal carriers, because its tall spikes were visible from afar. It may sound like the first practical navigation system, but once everyone planted their own, how was the poor postman supposed to know which blazing star was whispering the name of the correct recipient?
