I have several Canna plants. I am new to them. Someone on here kindly sent a picture of what the seed pods look like and where to find them on my Canna. Well, I found them. They are still green. However, today, a seed fell into the container from the plant (its planted in a large pot). The seed that fell is 1/2 black - 1/2 green. Is it too soon to scar it for planting or do I hold onto it until it all black? It's rather soft and small. The seed pods still on the plant are much bigger - 4 times!
Thanks Karen. I thought I just had to nick the outer pod until I see white then soak for about 72 hours...then plant the whole pod. Did I get that wrong? Also, since this pod fell off, then it can't be planted even if it does turn completely blackk?
If it does turn completely dark, it might then be good. But if you have lots of seeds coming on the plants, I probably wouldn't bother with just that one.
You don't nick the pod itself. You need to open up the papery sort of covering (the pod) over the seeds. Inside will be the seeds. Do this over a bowl as they are round and have a tendency to "jump". After you nick them until just the white shows a tiny bit, I think soaking for 24 hours is enough.
Yep, open up that papery part - the seeds are inside -- look a lot like dark B-Bs - and watch out or they'll jump out and be all over the floor, and you'll be looking for them. LOL. When I opened up some pods recently to send the seeds to someone, I was surprised to see that all the pods did not have the same number of seeds in them. I suppose it may be because I have several kinds of cannas. Otherwise, the seed pods and seeds looked very much like each other.
Cissy is correct. Any seed pod needs to completely ripen on the plant. There are some who are doing hybridizing and playing around with "green" seeds, but that's a specialized area. Leave it until it's brown/black like Cissy's photo, and you'll be fine.
Hello folks, this is great info above! I have a question though. If I deadhead my cannas, will it help promote more blooms? I have been doing this but I am not sure this is the case with cannas as with other plants.
Does anybody know?
Help! I bought some canna seeds and planted them in a Jiffy greenhouse, in peat pellets with a dome over them. I think I might have overwatered them a bit? Anyways, one is already coming up, it has white roots, which have pushed itself through the little pellet and a pretty green stalk. Really tiny though, not like one from a Rhizome. I have not allowed them to get direct sunlight yet, just left them in the domed greenhouse with pellets for 10 days now. Should I be letting them get sunlight without the dome on? When? And how long does it take for them to grow. I planted about 53 of them, each in individual peat pellets. Any suggestions and advice is greatly appreciated, I am new to gardening so please help me out here?
Dean: Thanks, I noticed that some one said it could take 6 weeks to see them growing? The pellets are still moist yet; so, thought about sticking them outside for just a bit on a warm day; but, not for too long, as it is hot here now. But shouldn't I wait until they start to come up? With my Rhizomes, I just put them in pots and then put them on the deck. I tried something different with the Rhizomes this time too, I started them in Miracle Grow Moisture Mix instead of what I usually use. I know Cannas love the sunshine.
I have several Canna plants. I am waiting for the seed pods to turn black so I can harvest them for replanting. However, several of them have fallen off while still greenish! this means they won't "ripen" to black so the seeds have a chance to be viable? :(
Joy, I had some pop up after two weeks. I usually put them in plastic food containers with perlite and put them in a south facing window. Once they start leafing out I pull them out of the container. I then plant them into one-gallon containers in the shade. Yes, wait tell they come up, I would say. Did you nick the seeds before planting them? I use a small file and a pair of vice grips to hold the seed. Just slightly file tell I see a bit of white. I find for tubers any good quality potting soil will do.
Cissy, some cannas are sterile. They are hybrids and don't produce seeds. I don't know if that's what you have or not.
Cissy, if they fall off they won't ripen. If and when yours produce seed pods they would dry out on the plant. Once the pods turn brown and dry out you'll be able to harvest the black seeds within. Good luck.
Dean: Thank you for your input those are lovely pics. Here where i live we have lots of clay and sand, so I usually buy dirt to plant flowers in. LOL Then I have my brother bail out the clay and replace it with potting soil and then plant my cannas in the ground. I like to leave them in pots myself until they mature and then put them in the ground. The ones I have planted now, the seeds, I plan on transplanting to pots and keeping them indoors until this Spring. My daughter will complain, as I have about 50 of them planted; but, there is room for them in the family room where there is a huge bay window and a pool table, perfect for covering with plastic and then plywood and putting the plants on to receive sunlight until they are nice and strong and Spring is here, then I will have some mature Cannas to transplant to the flowerbeds.
Dean: Actually there are 56 canna seeds planted in the pellets, I started a new batch about 9 days ago, there are 11 salmon, 11 red, 12 rose, 11 white and 11 yellow ones. I'm seeing the starting of 8 stems already, can't quit peeking under the dome. LOL This new batch I let soak for 48 hours and then nicked them just til I saw the white rubbing the dark seed covering off first, then I soaked them again for 24 hours before planting them in the expanded peat pellets. I then placed the dome on them; but, of course, can't quit peeking under the dome. I sat them on a stool inside the bay window.
Dean: I was really surprised and feel like a hen with her baby chicks here; I peeked under the dome and lo and behold there are 12 little bitty stems sprouting already and two have itsy bitsy leafs already. It's only been a little under two weeks, so I'm really excited here.
I know, they sprout so quickly once you knick them. My one-gallon containers of cannas that I sprouted from seed earlier this spring are growing into the ground. I guess I'll trade them for palm or cycad seeds.
Dean: Cannas are the only flower I am planting in the beds next year, I love them, you mentioned using pearlite? I notice that no matter what brand of potting mix or potting soil I use in pots they seem to want to turn to cement on the top and that is not good, why is that? Should I add pearlite to the potting mix or potting soil? I heard that coconut was good also, as it is light, and will not cement together, that bothers me, because then I fear that the roots are not going to get proper nourishment. Should I break up the soil or mix?
I am living in sunny Florida; but it is the NW part of Florida and come November we start to get pretty chilly, so, don't want to put the baby cannas out on their own, cause come December, January and February it can get pretty cold here, as I have a huge deck I can always put them outside on the not so bad days for just a bit and I have a south facing window and a bay front window where they can get direct sunlight, I will keep the heat indoors at the right temp and come March, they will be ready to hit the beds.
I use a variety: I used Miracle grow potting mix, then switched to the moisture grow potting mix and also have some seed starting mix. I have the ones that have grown big enough to get into pots in the moisture grow right now. I started all in peat pellets. Just before March, I'm going to use the Mantis to til in the left over jungle grow from my veggie grow boxes. As the dirt here is almost all clay and I think the jungle grow mixed in with it should be great for the beds. I gave the ones in the beds fertilizer last week, the kind that you attatch to the miracle grow water sprinkler attatchment and then this week hit them with the systemic. Now in March I will water them with water and Murphys soap and then treat with Sevin and Neem Oil. I've been collecting cut off leafs and letting them stay in a container that has holes in them and slowly rot, then will probably place these around my cannas come November. Only 12 of the 50+ have started sprouting so far, and 5 I transplanted to pots, the other 7 aren't quite big enough yet and the others are a bit slow.
Dean: My cannas now have leafs on them, how long before they are able to tolerate the sun in Florida outside, I've been moving them out for a few hours on the deck each day; but, no longer than that. I put them in pots just about a week ago from the peat pellets I had them planted in. How do you judge when they are ready for the flower bed? I don't want to put them out to quickly to fight on their own the sun ya know?
I think I did it right. When I was filing, there seemed to be two layers. Now that they are soaking, the first layer is lifting. The second layer was thicker and once filed through exposed an opaque center. I filed till the white spot was about the size of the tip of a ballpoint pen.
I bought some dwarf canna rhizomes and planted them in a pot that was about 12 inches deep. Only about four of the five bloomed at all and that was only once all summer. They were in full sun and were watered frequently. What did do wrong?
David, I think you need to make that a little bit bigger. Cannas from seed are funny. I planted 12 last winter and only 8 made it and out of those only 6 bloomed so you just take chances with them. You need to keep the soiless mix moist and if it starts to mold put sand on th top. BEV Here is my first baby only 18 inches tall in the ground and I got 4 rizomes from her.
Dragonfly: What a gorgeous canna. Mine have sprung up, it took a while; but you can't rush them sometimes. You just gotta be patient. I transplanted all of them into the ground and they finally made themselves at home in the beds, no blooms yet; but then again, it's coming fall so don't expect that til Spring. All my cannas are confused right now, as they are experiencing new growth and dying back, due to the hot/cold weather we are having right now. I've been going from AC/heat constantly lately.
Joy you do know that any canna that you grow from seed is a complete new plant don't you. It takes three yrs for them to stablize. You can patent them and name them if you want. I just can't wait to see what this one will do the next two yrs. I don't have the resourses to patent but will enjoy them. I named this one "Bev's Beauty" I have a couple others that are very nice too. Here is one. BEV This is" Lemonaide"
