Panicum virgatum 'Warrior'
A very well behaved switch grass which has beautiful airy purple flower heads that bloom over a long period.
It tolerates a wide range of soils, including dry ones, but prefers moist, sandy or clay soils and tends to flop in rich soils.
Generally best in full sun though it will grow in part shade, but begins to lose its columnar form in too much shade.
Cut back clumps to the ground in late winter to early spring.
Wonderful autumn colour.
