Giant Canna Ambassador (Black Knight)

Bold flowers and dramatic foliage make Giant Canna Ambassador (Black Knight) a standout in beds and borders. Velvety red, showy flowers start blooming in midsummer—and they'll keep blooming until the first fall frost. Bronze, tropical-looking leaves add to the plant's beauty. Growing up to 4' tall, Giant Canna Ambassador (Black Knight) makes a bold statement in the sunny garden. Cannas have been long valued by park and municipal gardeners, and now home gardeners realize the value of these new hybrids as each year their popularity grows.
