Best grown in moist, organically rich, well-drained soils in full sun. Rhizomes may be left in the ground in USDA Zones 7-10, however in colder regions, the rhizomes should be lifted in fall for overwintering. Plant rhizomes 4-6” deep and 18-24” apart in spring after threat of frost has passed. Remove entire flowering stems immediately after bloom. In fall, cut plants to the ground after first frost and lift rhizome clumps for winter storage in a dry medium (peat or vermiculite) in a cool dry location than does not fall below 40 degree F. Rhizomes may be occasionally sprayed with water in winter to make sure they do not become so dry that root shriveling would occur. Container grown plants can be stored in their containers in winter. Propagate by division in spring before replanting outdoors.
Cannas are large rhizomatous tropical plants that produce flower spikes
in summer atop erect stems sheathed in large paddle-shaped leaves.
Big bold and colorful with heights ranging from 2'-10' the Canna is one of the most versatile and cost effective perennials for the southern garden. They flower in the heat of mid-late summer when many other plants give out. These lush plants give areas of the garden the feeling of the tropics, while they actually take on the role of the summer garden 'bones' and backdrop. The smaller cultivars, however, fit in nicely as excellent centerpieces for patio planters. With lance-shaped leaves of green burgundy and even multi-colored stripes along with flowers of bright red, yellow, coral and multi-colors, the possibilities are endless as to where and with what combinations cannas can be planted. Responding to ample moisture, full light and rich soil, they are even happy planted in a pot submerged in a pond; they can be considered ‘cut and come again plants’ if their leaves become damaged during the growing season; Grade #1 tuberous rootstocks; plant 10”-18” apart; whz 7-10; treat as an annual or container plant, starting indoors with bottom heat in zones 3-6 because they hate cool soil!
Genus name comes from the Greek word kanna meaning a reed.
On the Black Knight Canna grow bright masses of vibrant red flowers, sometimes with darker edges. However, the real beauty on this plant is the dark almost black foliage, giving it an almost mysterious look. Growing tall and sometimes up to 36" wide, this canna needs some room to showcase all of its splendor! Hummingbirds like these!
Group or mass in beds or borders. Effective planted with both annuals and perennials. Foundations. Large containers. Leaves are particularly impressive when back-lit by sun.
