Canna Tropical summer is a dwarf Canna series from seed so it is not prone to diseases transmitted in rhizome production. Heavily branching plants bloom in approximately 90 days from sowing with continuous flowering. Tropical Rose is an AAS award winner.
Canna seed propagation is not as easy as the seed collection. The seeds do not germinate when planted directly in the soil. The tough seed coat is the main obstacle. Canna seeds have to be prepared beforehand by softening the seed coat to encourage germination.
Canna seed propagation involves soaking, heating and scarification. Sometimes it takes a few attempts to get it right. You should start the process at least one to two months before you plan to plant it outside. Germination usually takes one to two weeks
Soaking – Canna seeds should be soaked in water for a minimum of 24 hours. Some recommend using lukewarm water for soaking. Make small depressions in the medium and put in the seeds. Cover with the mix and water. After planting the seeds in the medium and watering, the container should be covered in plastic wrap and kept warm indoors. A constant temperature of 70 to 75 F. (21-24 C.) is necessary to initiate germination. You can use a heating pad to maintain the temperature.
Scarification – Another method to encourage canna seed germination is by rubbing off a bit of the seed coat before planting. Use a file or sandpaper to scrape off the seed coat. You should keep rubbing until the whiteness of the endosperm becomes visible. Scarified canna seeds can be planted directly in the medium without soaking, as water can easily get across the seed coat now. But the container should be kept warm throughout. Canna lily is a monocot, with just one seed leaf emerging first. When the seedlings are over 6 inches in height, they can be transferred into pots. Planting in the garden should be attempted only after all danger of frost is over.
Canna Tropical summer Plants are 24 to 30 inches (60 to 75 centimeters) in height.

In seed tray it is important to sow Canna fairly deep (1.5 times its diameter or more) otherwise upon
emergence it tends to push itself out of the soil.
• For best branching, when transplanting, the seedling should be planted so that the final soil level is
right up to the level of where the first set of leaves flare out.
• Also for best branching, it is recommended to plant Canna in pots no smaller than 6”. Root space is
key to the later success of this plant.
• Prune off spent flower stalks to encourage new blooms.
