Cannova Canna Lilies are now available at Sunshine Horticulture! Four great colors, red with burgundy foliage, rose, yellow and red with green foliage, available in 72 cell trays. All of these come from virus free seeds.
Suggested pot size: 1 gal/ 6 inch or 2 gal/ 8 inch
Due to canna Cannova’s unique compact habit and excellent branching, they can be finished in a wide range of containers. Cannova can be finished in a container as small as a 41/2-inch pot, but still will finish out a 1- and 2-gallon container with additional grow time and plants per pot. For containers from 41/2 to 61/2 inches one plant per pot is recommended. An 8-inch or gallon can be finished with one plant per pot, but two or three plants per pot will finish faster.
Although not necessary for larger containers, if height control is needed it can be accomplished using a 1- to 4-ppm Bonzi drench two weeks after transplant.
Canna Cannova grows better than other seed cannas under cooler conditions. However, for best results daytime temperatures should be 70 to 85° F and nighttime temperatures should be 60 to 80° F.
Media and Fertility
Cannova should be planted using a well-drained potting mix with an EC of 1.0 to 2.6 for finishing (calculated using the pour through method). During the plug stage, EC should be below 0.5 before cotyledon expansion. As the cotyledon expands, the EC should be raised but kept below 0.75, up until the first true leaf growth. Finally as the plugs are finished the EC should continue to be raised to 0.75 to 1.2. The pH should be kept between 6.2 and 7.0.
Days To Flower
The entire crop time for Cannova from sow to flower is 80 to 110 days depending on finishing temperature and light.
