Characteristics of Liatris spicata ‘Kobold’
Liatris spicata ‘Kobold’ is a herbaceous perennial forming a compact clump of narrow, linear leaves. In summer, upright flower stems rise above the foliage and carry dense spikes of small purple-violet flowers. Unlike many spike-flowering perennials, Liatris flowers open progressively from the top of the spike downwards. ‘Kobold’ differs mainly from the typical species through its more compact growth, usually reaching around 50 cm in height. The above-ground vegetation dies back in winter before regrowing from the crown in spring. Its good hardiness makes it suitable for planting in many regions with cold winters.
How to use Liatris spicata ‘Kobold’?
Liatris spicata ‘Kobold’ is particularly suitable for perennial borders, sunny edging and naturalistic planting schemes. Its upright, compact habit creates strong vertical accents without obscuring lower-growing plants nearby. Planting several specimens together enhances the visual impact of its purple flower spikes. It combines well with Echinacea, Achillea, Rudbeckia and ornamental grasses that appreciate similar growing conditions. The cultivar can also be grown in a large container using a well-drained substrate. Its flower stems are suitable for fresh or dried bouquets, making it a useful choice for cut-flower gardens as well as ornamental planting schemes.
What are the best cultivation tips for Liatris spicata ‘Kobold’?
Plant Liatris spicata ‘Kobold’ in full sun in loosened, fertile and well-drained soil. Allow approximately 30 to 35 cm between plants, equivalent to around 8 to 10 plants/m² for a rapidly established mass effect. Water regularly after planting to encourage root establishment. Once well established, the plant tolerates periods of drier soil, although additional watering may still be required during prolonged drought. Avoid excessive winter moisture around the crown. Remove faded flower stems after flowering or leave them temporarily for their structural effect. Cut back dry growth in late winter. A moderate application of mature compost in spring is generally sufficient in open ground.
