Liatris spicata 'Kobold'

Dense Blazing Star

Liatris spicata ‘Kobold’ (Blazing Star / Gayfeather) is a compact, upright perennial with a clumping habit, featuring narrow, grass-like green foliage and dense spikes of vibrant rosy-purple flowers that bloom from top to bottom in mid to late summer. This dwarf selection is valued for its strong vertical form, pollinator appeal, and suitability for smaller garden spaces.
