Growing from seed is very rewarding and exciting
Grow from seed
To promote the benefits of gardening on physical and mental health.
Follow the suppliers instructions. As I cannot provide the the constant heat required I sow the seeds and put them a double radiator in our conservatory usually in January. Ensure that the compost does not dry out. Once germination takes place place them on the window seal. Check regularly and pot on when there is a substantial root ball but not pot bound.
Please do try and Canna grow from seed as they have a good
germination rate and given the cost at the garden centres it is a very cost effective way of producing more plants. Also division, one year one plant the next year three. You will need to use a file or saw to score the seed casing which is quite thick and without doing so the seed will not be able to germinate. In the wild prairie fires weaken the seed casing and allow the seed to germinate. I find it helpful to hold the seed in monkey wrench unless you are young and fit as you have to grip the seed quite tightly. Buying on line instructions include soaking for 24-48 hours which I did not need to do with my home grown seed. At the end of the year search online for suppliers like HimalyanGardens and JungleSeeds which I use regularly.
A lot of the time it is pot luck. Not all plants have evolved to produce 100% viable seed. I have found that some corms may not grow for a year or two so do not throw them away and do not over water them. They will rot. I bought three Curcuma Longa three years ago at a plant fair at Hyde Hall and one has decided to grow and flower which it did in 2018. Beware that by February/March some plant material may have sold out. Have to say that I get very exciting watching the seeds germinate.
The Cannas I have grown from seed are Ra, Cannova Bronze Scarlet , Tropicanna Red Bronze, Firebird, Perkeo and Teurkheimii.
