How to grow liatris

Liatris roots are generally planted in spring, once the ground is workable. Plant them soon after they arrive rather than storing them for long periods. They can also be started in pots and grown on before planting into the border later in spring.

Plant Liatris with the roots pointing downwards and the crown or growing buds facing upwards. Cover the rootstock with soil so the buds sit just below the surface, then firm gently and water well. Choose a position where excess winter water can drain away easily.

Look for the small buds or growing points, which should face upwards, with the roots underneath. If the rootstock is difficult to orientate, planting it on its side is safer than positioning it upside down; the new shoots will naturally grow towards the surface.

Liatris generally flowers in mid to late summer, usually from July into September depending on the variety and weather. Its spikes are distinctive because the flowers begin opening at the top and gradually work their way downwards.

Yes. Liatris is a hardy herbaceous perennial and can return for many years when established in suitable conditions. The foliage dies back after the growing season, while the underground rootstock remains dormant and produces fresh growth again in spring.

Liatris performs best in full sun, where it develops strong upright stems and flowers most freely. It can tolerate some light shade, but too little sunlight may result in weaker growth and fewer flower spikes.

Liatris prefers well-drained soil and generally copes better with summer dryness than with prolonged winter wet. Avoid positions that remain waterlogged, as excess moisture around the dormant rootstock can lead to rot.

Yes. Liatris is an excellent pollinator-friendly perennial, attracting bees, butterflies and other insects to its densely packed summer flowers. Its relatively late flowering season also makes it useful for extending the supply of nectar through the garden.

Yes. The tall, straight spikes make Liatris particularly useful for fresh and dried flower arrangements. Cut stems when the upper flowers have begun to open but much of the spike is still in bud, giving the remaining flowers time to develop in the vase.
