How to plant
When to plant
Plant Liatris corms in spring once the soil has warmed. In mild climates they can also be planted in early autumn, giving the corms time to root before winter.
Where to plant
Choose a sunny location with at least 6 hours of direct sunlight daily. Liatris thrives in meadows, prairie gardens, pollinator beds, gravel gardens and sunny borders. It dislikes shade and damp, heavy soils.
Preparing the soil
Loosen soil to 20–25 cm and ensure sharp drainage. Liatris prefers sandy, loamy or gritty soil. Improve clay with coarse sand or grit. Avoid very rich soil, which can cause floppy growth.
Preparing the corms
Select firm, healthy corms. Do not soak them. Plant soon after receiving, as Liatris corms prefer not to sit in storage for long.
Planting the corms
Plant corms 5–8 cm deep with the flat side down and the pointed side up (if visible). Space 20–30 cm apart depending on variety and desired density. Water lightly after planting.
After planting
Keep soil lightly moist during establishment. Liatris grows quickly once temperatures rise. Avoid heavy watering, as corms can rot in soggy soil.
During growth
Water during prolonged dry spells, but allow soil to dry between waterings. Remove spent flower spikes to encourage tidy growth and prevent self-seeding if undesired. Taller varieties may need support in windy areas.
After flowering
Cut back stems once they turn brown, or leave them over winter for wildlife and structure — seed heads attract birds. In late winter or early spring, tidy the plant by removing old growth.
Extra tips
Liatris is excellent for pollinator gardens, prairie borders and cut-flower arrangements. It naturalises gently over time and returns reliably each year. Combine with grasses, echinacea and rudbeckia for a classic prairie look.
