Acanthus spinosus (Acanthaceae)
Spiny leaves set this Acanthus apart from other species and add a tropical feel to the garden. Bold foliage is further enhanced in early summer when stiff flower spikes bearing hooded dusky-purple flowers rise 2-3' above the leaves, adding a unique tall and vertical texture. Plant in well-drained soil; part shade is best in the South.
