Verbena bonariensis 'Tall Verbena'

VERBENA BONARIENSIS
Tall Verbena
Verbena bonariensis

This tall plant has long thin stems topped with clusters of tiny purple flowers that appear to be suspended in the air.  Works well where some structure is needed while still having a delicate feel. 

Will self-seed. Borderline hardy, may be damaged by winter frosts, avoid this by leaving the dead stalks until spring, when new growth is evident, before cutting them back. A protective mulch should be added around them in the autumn with leaf mould or compost.
