Tall spikes bearing dozens of dark violet-blue flowers rise up from the deep green, roughly textured foliage of this shade garden perennial to create a riot of color for the springtime garden. In more shaded areas plants may require staking as the flower stalks often bend with the wait of the blossoms. Use in containers, shaded beds or perennial borders. In flower plants reach 2’ tall with an equal spread. Hardy to 0F. Garden origin.
