A genus of about twenty species of hardy perennial or biennial flowering plants of stately habit, bearing racemes of funnel-shaped flowers. They thrive in any soil or situation but prefer a shaded spot under the limbs of trees or among tall-growing shrubs where they give a fine effect in early Summer.

Propagate by seeds sown out of doors, in June, and covered very lightly. After the first rains in the Autumn, plant out the seedlings about a foot apart.
