Liatris spicata 'Kobold' is a compact herbaceous perennial with tidy clumps of narrow green leaves and upright flower spikes in summer. The blooms rise above the foliage in rich purple shades and add strong vertical color to borders and mixed plantings. It is a good choice for smaller gardens because it stays more compact than many other blazing stars. The flowers also make it useful for cutting and arranging.
This plant grows best in full sun and well-drained soil, where it keeps a neat, upright look through the season. It works well in pollinator plantings, flowering borders, and natural-style designs, and it is often valued for attracting bees and butterflies. It is not a houseplant and is grown mainly as a hardy outdoor perennial. The foliage is plain green rather than variegated, which gives the flowers even more contrast. It has no notable scent.
Care is simple and well suited to average gardeners. Spent flower stems can be removed for a cleaner look, and the whole plant can be cut back once the season is over or just before new growth begins. Division is the easiest way to make more plants and helps keep older clumps vigorous. In wet or crowded conditions, it may develop rot, leaf spot, rust, powdery mildew, or wilt, while young shoots can also attract slugs and snails. Good drainage, sun, and air movement help keep it healthy and flowering well.
