I want to harvest the seeds from my cannas but am not sure if I take the (I don't know what it's called) - it's round with bumps and almost hard fuzzy things on it - I'm calling it a seed capsule, but I'm sure it has a name (ovule maybe?) Anyway, do I wait until it turns brown and kind of hard or do I take it off while it's still green?
Also, I know the seeds are various sizes... what's the smallest one anyone knows of?
My cannas have not produced seeds yet.
I think that I would not harvest them while green.
I would be waiting until the capsule turned brown.
Perhaps someone with more experience will come on line,
and give you a better answer.
In Ian Cooke's book on Cannas, he says the seed is not ripe until the capsule is brown and brittle.
The seeds are then dark brown almost black.
Most canna seeds are about the size of peas or a little larger.
gardenjeannie, I just harvested some canna seeds and they are dry and dark brown. They are about the size of english peas. But when do I plant them? Do I need to straitify them in the frig? Someone tell me what to do. Thanks alda
I have been growing canna from seed this year. I remove them from the plants when the "pod" splits on it's own. Then I put them in a open container until they dry some so they don't mold. If you plan on keeping them for some time the frig is a good place as it will keep them from drying out too much. The sooner they are planted the better. I don't nick them and you certainly don't need to cold stratify them as they are semi-tropical and don't naturally live where it gets cold. If you plant them immediately they seem to do best. I pot them up in my unheated greenhouse in gallon pots and they germinate quickly, within two weeks.
I am no expert but maybe they aren't getting pollinated? I have this happen sometimes too.
And sometimes there will be 12 seeds in the dried pot and sometimes only 2, that seems like it has to do with pollination to me.
So now I had better take good care of the root when the foliage dies off.
I have two that were labelled as Tropicana. One has red striped leaves,
but has not flowered yet. The other has green leaves and pink flowers.
That is the seed capsule, not the seeds. That capsule does not look it pollinated.
That small flower variety will most likely produce seeds. The plant may need more maturity.
Or better weather conditions. Give it a little more time to see what it does.
