Growing canna: Cannas need full sun and grow best in a deep, rich, moist but well-drained soil. Incorporate extra organic matter and a slow-release fertilizer in the soil before planting. For earliest bloom, start in pots indoors. Otherwise plant roots directly into the ground after soil is warm and all danger of frost has passed. Use pieces of rootstock with 2 or 3 large eyes and plant 2 inches deep. Space 11/2 to 2 feet apart. Remove spent flower heads for more prolific bloom. In fall after the first light frost, cut back stems to 6 inches, dig roots with soil attached, and store in a cool, frost-free place. While in storage, water sparingly.
Propagating canna: By seed or by division of roots. Seed propagation is slow; cut roots into pieces, each with 2 to 3 eyes, in the spring just prior to planting.
Uses for canna: Use cannas in the center of island beds, at the sides or back of brightly colored borders, or near pools and ponds. They also dominate large containers.
