Canna is one of the most popular tropical foliage plant used in gardening. The unusual greena and white foliage, along with it's striking 4 to 5 feet height, make this canna stand out from the crowd.
Canna can be planted anytime of the year in southern zones but the soil temperature should be 78-80° F. In zones 3-8, plant in spring and summer when ground temperature is not below 65°F. They should be started indoors one month prior to moving outside. Canna prefer a sunny location in moist, fertile soil. When planting outside, prepare soil by spading and adding compost or rotted manure. Rhizomes should be planted 1 - 1/2" deep and spaced 18-24" apart. Soak well after planting. For container planting, pot one rhizome per gallon in well drained potting mix. Containers will finish in 10-12 weeks when potted during the appropriate temperatures: Daytime 70-75° F; Night 65-70° F. Fertilize established (2-3 weeks) plants monthly with 1:2:1 ratio (12:24:12 or 5:10:5), fertilizing at 1/2 the package recommendation. NPK at 200 ppm weekly in injector fed systems.
