Liatris spicata

Description

Liatris spicata is a highly ornamental perennial plant valued for its upright flower spikes and elegant habit. It forms clumps of narrow, elongated green leaves, and in summer it produces dense flower spikes that add height and structure to the garden. It is widely used in borders, perennial beds, natural-style planting schemes, and large containers.

Origin

Liatris spicata is native to North America, where it grows in prairies and open sunny areas.

History

Over time, it has become a much-loved garden plant because of its vertical flowering habit, its hardiness, and its strong attraction for pollinators. It is also widely used both in gardens and as a cut flower because of its distinctive spike-shaped blooms.

Care

It is a hardy plant and fairly easy to maintain.

• Light: needs full sun.
• Soil: prefers well-drained soil, light or moderately fertile.
• Position: ideal for borders, perennial gardens, ornamental meadows, and large pots.
• Resistance: tolerates heat well and, once established, can cope with dry periods.

Watering

Watering should be moderate.

• During the establishment period, it benefits from regular watering.
• Once established, it tolerates drier conditions better.
• It is important to avoid waterlogging.

Pruning

Pruning is simple.

• Dry flower spikes can be removed after flowering.
• Dry or damaged leaves should also be taken away.
• At the end of the season, the clump can be generally cleaned up.

Curiosity

One of the most interesting qualities of Liatris spicata is that its flowers are very attractive to bees and butterflies. Its upright form also creates strong contrast with rounder plants or looser flower shapes.
