Growing cannas.
These things grow pretty fast
My question is this: will it harm them to put them out in my greenhouse all day in full sun or do I need to do it by degrees? They get like 5 hours of sun through the window.
also - will I need bigger pots eventually? Thanks in advance

Growing Cannas from Seed
Comments (4)The purchased seed should work fine. Seed is not a problem if the pollination of the plant producing the seed is controlled. The seed produced in your garden is from a plant produced from a cross and can revert to either parent or anything in between. The purchased seed will be an F1 cross where both parents are known and the resulting seed is predictable, though not as predictable as a plant produced from a vegetative part of a plant with no sex involved.

Comments (1)I used pet nail clippers for my seeds. Make sure to file/clip the opposite side of the scar on the seeds(that is where you will see a white root poking out after soaking). I then soaked them for 48 hours changing the water occasionally with warm water. I used a seed growing kit with a seed starting mix. Keep them moist at all times. I placed the seeds under a T5 plant growing light. They germinated within 3 days, and it is now day 14 and the seedlings are 6 inches tall growing their 3rd leaves. They take off very fast. Once you see the roots sticking out of the bottom, transplant them into a 4" or 6" pots, I transplanted mine into plastic drinking cups, once they grow out of those, they will be planted outside. If you want to purchase any more seeds, get them from Karchesky Canna online, 15 out of 16 seeds i got from Alice germinated, now that is a pretty good germination rate. I also purchased rhizomes from her and they are growing very tall and vigorous. Good luck to you...See MoreHow do I grow cannas from seeds?
Comments (0)Canna seeds are tough. For best germination, they should be nicked. To nick them, you can use a file, a grinder, or even a drill to drill into the seed a little. You just want to break the hard surface of the seed just enough to see a little bit of the creamy white interior of the seed. After nicking, soak the seed in water for a day or two. You should see the seeds swell as they soak up the water. Then plant in moist soil. Keep the soil moist and warm and your seeds will sprout. If started early, like during winter in a greenhouse, cannas grown from seeds can bloom the first year. However, the seeds from the hybrid cannas do not produce plants like the parent plant. They usually revert back to the small flowered type with traits of both the wild canna and the parent. Once in a great while, you may get lucky and a viable canna will grow from one of those seeds, but it doesnt happen often....See MoreAnyone growing Canna musifolia in 8b PNW zone?

2 years agoTo me, the word aficionado just means that you appreciate them. And yes, they remind me of tropical places I've visited throughout the years. For some reason, I always try to add more tropical plants to my summer outdoors.
According to some other threads on Gardenweb, you should be fine at 40 degrees. Here's one:

Here is my trolley. There are only two showing signs of life: Cleopatra (she is the over-achiever this year) and a red variety that I no longer have the name. The rest have yet to emerge and they have been out since April 1.
I'm a little worried that some may have gotten too cold over the winter in the garage. We had a really cold spell this winter. But it's too early to give up on them.
These have been out overnight for the past few nights. But I'm still not quite ready to move them to the uncovered porch. Just because if we do get snow, it will be harder for me to protect them. when they are on the trolley, it's easy to just roll back into the garage.
