Germinating Canna Lilly Seed
Last September, in France, I came across a splendid Canna. Very splodgy,
orange/creme flowers with variegated red/green leaves. Some of the flowers had set some good seeds - which I picked. Seeds are quite large and hard - I presume they'll need cutting to stand any chance of germinating. Has anyone grown Cannas from seed? Suggestions? What are chances of germination? How long until they flower? Regards, -- Larry Stoter |

I didn't file or cut the seeds, but just put them in a pot in early spring in the GH and left them to it :~)) I covered the pot with plastic to keep the soil moist and most of they germinated fairly quickly. As far as I can recall they took a couple of years to reach flowering age. More info at : http://www.pwbelg.clara.net/canna/ HTH , Jenny |

Germinating Canna Lilly Seed
I have germinated one (of four) seed this autumn, now sat on the kitchen
windowsill having grown quickly to 6" or so since October. I placed the seeds on moist compost in a freezer-bagged pot in the airing cupboard. Only one of four seeds germinated, and it took about 4 weeks. In hindsight, I'd use individual pots and just leave them in until they either germinate or I need the room for laundry.. . Al.

I've had flowers in the first year from a February sowing - seed from one of the commercial suppliers. the original post's description sounded very much like Canna Durban - unlikely to come true from seed, me thinks! pk |

Germinating Canna Lilly Seed
I grew canna from seed it took 3 summers before it flowered. Id suggest
growing them from Ryzone. Currently I have 20 bushels in a cold cellar for the winter. Cannas make the yard look so tropical, my cannas grow 9 foot tall. |

How long until they flower? Sounds as though the variety you have collected may be 'Cleopatra' a hybrid that can have red and green, all red or all green leaves as well as red and yellow, all red or all yellow flowers. It is quite a curiosity and great fun to grow. However, it should be noted that Canna hybrids do not come true from seed and although some of the progeny may resemble the parents, they are rarely as good. Nevertheless, it is fun to grow a few this way and you never know, you might just get something that is even better. The best time to sow is in January or early February , which will give the plants a good 14 - 16 weeks growing time before they can be hardened of for planting out of doors. Thankfully Cannas are extremely easy to grow from seed if you observe a few easily followed rules. The seed coats are bullet hard (hence the occasional common name of 'Indian Shot'). The best way of enabling water to penetrate this seemingly impermeable barrier is to nick the seeds, by holding them in a pair of pliers and using a file, carefully cutting into the coat until you reach the white endocarp within the seed. Only the tiniest amount needs to be exposed and it is better to file too little away than too much. If you look at the seed carefully, you will see a scar (hylem). It is through here that the growing shoot will break through. You should file the coat on the opposite side to the scar in order to avoid damage to the embryo. The next step requires a bit of bravery, so you'll need to 'grit yer teeth'. Place the seeds in a cup or beaker and pour freshly boiled water over them. As soon as you hear the seed coats starting to crackle and pop, immediately add enough cold water to cool them down to luke warm. The seeds should then be allowed to soak for 24 or more hours in a warm place - an airing cupboard is ideal. Inspect the seeds and most should have swollen to almost double their original size after 24 hours. Sow these just below the surface of lightly moist, sterilised, soil-less compost and maintain temperatures of 25C or higher. Germination will take no more than 48 - 60 hours and don't be surprised to see first shoots appearing in as little as 24 hours. Those seeds which have not swollen immediately, can be left to soak for another day or so before sowing. In the early stages, seedlings need to be kept at around 21C to prevent damping off. Canna seedlings need lots of light and should be left to grow to the second leaf stage before potting up into 8 - 10cm, diameter pots. Once they have established well, temperatures can be gradually reduced to 15 -18C. Pot on as necessary and keep the young plants moving by applying half strength liquid feed at 14 day intervals. By May, the seedlings should be in 25 -30 cm. diameter pots and will be ready for hardening off for planting out in the first week of June. If you start early enough in the year and maintain good growing conditions, you can expect first flowers by July or early August. Dave Poole TORQUAY UK |

Larry,
That was the most informative post I ever read! I just came home from the local botanical garden. I happen to find 36 golden Canna seeds and didn't know what to do with them. I must say, the boiling water sounds a little scary. I'll try it though -you sound like you know what your talking about. I'm so glad I tripped over this website- my new favorite! thanks Larry Quote:

"haplocom" wrote I'm so glad I tripped over this website- my new favorite! Website??? It's a Newsgroup, part of Usenet, the original part of the internet. Gardenbanter just use this newsgroup sometimes but don't tell anyone what we are and that you can deal directly. If you are using Outlook Express as a Mail Reader then, when online, go to "Tools" and click "Newsgroups" it will then look for all newsgroups on your ISP's server, probably 30,000 or more so it can take a while. You can then search for the interesting ones amongst those, go to them and have a look, and subscribe (it's free) to any that interest you. Then when you click to open the files on OE, near the top on the left, your newsgroups will appear underneath "Inbox", "Deleted Items" etc, and you just have to click on them to download all the latest messages, replies, and post your own. |
