Blazing star, botanically known as Liatris spicata, is a herbaceous perennial valued for its upright growth and striking flower spikes. It develops narrow, grass-like foliage and produces tall spikes of purple flowers that bloom from top to bottom during the growing season. This plant adapts well to temperate climates and performs best in full sun with well-drained soil. Blazing star is commonly used in borders, garden beds, and naturalized planting, where it establishes steadily from seeds and tolerates dry conditions once established.
