Of all the ornamental grasses, of which there are many, purple fountain grass (Pennisetum setaceum ‘Rubrum’) is probably one of the most popular. The purple or burgundy-colored foliage and soft, fuzzy-like blooms (which are followed by purplish seedheads) make a bold statement in the garden—on their own or grouped with other plantings. Growing purple fountain grass is easy and requires little maintenance once established.
