Blazing Star (Liatris)
Liatris spicata
Family Asteraceae
Blazing star does everything upside down — its fuzzy purple bottlebrush spikes open from the top of the stem downward, an oddity you notice about the same moment the butterflies do. A prairie native, it holds two to four feet of vertical color through the heat of summer.
From an underground corm it comes back drought-proof year after year, asks only sunshine and drainage, and moonlights as a long-lasting cut flower. Butterflies and bees work the spikes; goldfinches strip the seed heads in fall. Slip a handful of corms into the sunny border and wait.
