Pachystachys coccinea (Cardinal's guard)

Pachystachys coccinea is a perennial evergreen shrub cultivated as an ornamental and garden plant for its red flowers on flashy terminal spikes. It has escaped from cultivation and is often found naturalized in damp thickets and at forest edges. Presently, P. coccinea is only listed as invasive in Cuba and as a "common" alien species in Trinidad and Tobago.
