It should be noted that each of the three references individually have less information on Canna lilies than wikipedia's article.  ''Gardening for Dummies'' especially is not worth the purchase if all you are looking for is information on Canna lilies--it's got barely a paragraph on them.  [[User:Koyaanis Qatsi|--KQ]] 18:47 Sep 19, 2002 (UTC)

I love canas.  Simple. easy to grow. will tolerated a wide veriety of conditions.  They will do fine will a minimal amount of light, water, or nutrients.  But if you can maximize it's environmental influence, they are spacatular often reaching heights of 8 or 9 feet of more.  
Humming birds love them.  th, champaign,ill

== Meters as well as feet ==

Mention meters as well as feet. Priority on meters too.

== Recommended merge ==

I would suggest merging this article with [[Cannaceae]], since the genus Canna and family Cannaceae are identical, whereas "Canna" is somewhat ambiguous (although its use as a plant name is probably more familiar than its use as an island name).  "Canna lily" an atrocious common name--plain old "canna" is both simpler and more accurate, and is also fairly commonly used, at least in the United States. Canna (plant), Canna (genus) and Canna lily should all be redirected to Cannaceae. [[User:MrDarwin|MrDarwin]] 17:56, 16 February 2006 (UTC)

== Canna Species ==

The list of species seems to be based on the work of Professor Maas. However, Dr Tanaka has subsequently produced a revised list of Canna species, including some new species he discovered in South America. Should we not be quoting that classification of species?

== Semi-protection ==
--[[User:Giantsshoulders|Giantsshoulders]] 18:26, 16 September 2006 (UTC)
This page has been placed in Semi-protection to stop anyone from editing it. As it is very much a page under development, still inadequate in many areas, this seems a strange and arbitary move. Can someone explain why this has been done?

== Canna Category ==

After several hours effort I had all the Canna pages pointing at a single Cannas Category page, the same as every other major genus. I returned several hours later to see it all destroyed. This is blatant vandalism. No attempt to discuss, just arbitarilly destroyed. Why?
:It looks like the page was modified by an automated bot. These sometimes do things they are not supposed to do, or perhaps you made some kind of mistake in setting up the Cannas category. I can't answer your specific question so you should ask the question on the talk page of the user who created the bot--just check the page history.

== The lead photo ==

[[User:CannaCollector|The Canna Collector]] 18:50, 29 September 2006 (UTC)The photograph is of a red Italian Group cultivar (''x orchiodes''), and not Canna ''x generalis'' as the text indicates. What should be done with this image?

[[User:Giantsshoulders|Giantsshoulders]] 18:48, 29 September 2006 (UTC)In addition, the use of ''x generalis'' is deprecated, and the group name should be used instead, if at all.

I have a great photograph of the world's first Canna hybrid, C. 'Annaei', will that be more appropriate?[[User:Jumping Jack Flash|Jumping Jack Flash]] 19:01, 29 September 2006 (UTC)

[[User:217.33.199.77|217.33.199.77]] 09:36, 2 October 2006 (UTC)Indica was the first species discovered, seems most appropriate.

--[[User:195.93.21.34|195.93.21.34]] 19:07, 3 October 2006 (UTC) Solved it for you, keep the photo and correct the description!

==Cannas category==
[[User:Giantsshoulders|Giantsshoulders]] 17:41, 24 July 2007 (UTC)Why has the Cannas category been removed? I found that to be a great index to the genus and other associated articles and used it all the time.

:The genus is ''Canna'' not "Cannas," and you may create the category for the genus ''Canna'' and use it, if it has not already been created.  It should be created, in the last case, but you don't have to be the one to do it.  [[User:KP Botany|KP Botany]] 17:49, 24 July 2007 (UTC)
::Yes, ''Canna'' is a category, and it may be used.  [[User:KP Botany|KP Botany]] 17:50, 24 July 2007 (UTC)
:::I would suggest using "Cannaceae" as the category; this category already exists, most of the canna-related articles are already included in it, and it's rather redundant to have a separate category for "cannas". [[User:MrDarwin|MrDarwin]] 19:52, 24 July 2007 (UTC)
::::Apparently we're supposed to use genus level categories rather than family level, and make the genus a subcategory of the family.  I disagree with this, but I'm not fighting it.  Wikipedia will be one of the few plant sources that don't use families as categories, but, apparently, this is how it's supposed to be.... [[User:KP Botany|KP Botany]] 03:57, 25 July 2007 (UTC)
:::::Since Cannaceae is monotypic, [[:Category:Canna]] would be utterly redundant. In response to KP's comment: genus-level categories are used elsewhere where there are several genera in a family where the family category would be entirely too large if they weren't separated (imagine how large [[:Category:Orchids]] would be if it weren't broken down!). Generally, we're to use the most specific category we can. And it's not meant to be a statement regarding the other plant sources using families as the category. Because of the limitation of Wiki software to not display more than 200 entries for a category on one page, it is preferred to break it down when it gets too large. Genera categories are the way to do this with large families. Cheers, --[[User:Rkitko|Rkitko]] <sup><small>([[User talk:Rkitko|talk]])</small></sup> 13:25, 25 July 2007 (UTC)
::::::Do we have this written up on WP:Plants?  The limit of 200 entries is a bit difficult, because, in fact, biology did not give a nod to Wikipedia when creating the known universe.  But that's another battle.  If this is the case, make sure we have the policy up and get the ''Canna'' category deleted.  If we don't have the policy up, let's write it, and make sure that the ''Canna'' category is deleted and only Cannaceae used.  Sorry, Giants, for the inconvenience.  We can get a bot to reintroduce the categories to the pages, if necessary.  But let's wait until it's completely clear what we're doing, and it's in writing.  [[User:KP Botany|KP Botany]] 21:26, 25 July 2007 (UTC)

:::::::I don't think we do have this written anywhere--it's just been the consensus I've come across, but it would be good to have a conversation about it at [[WT:PLANTS]]. I was also going to reintroduce a conversation about additions to [[WP:NC (flora)]] regarding the consensus we came to over subgenera, sections, cultivars, etc. so we can make it formal in the naming convention (See: [[User talk:Ptelea]] for the reason I want to get our convention on cultivar naming set). I wonder if TOL has any guidelines on categories? --[[User:Rkitko|Rkitko]] <sup><small>([[User talk:Rkitko|talk]])</small></sup> 02:09, 26 July 2007 (UTC)
::::::::Sounds good, also the cultivars (see my comment about that).  It is much easier if we have the policy written somewhere, makes page moves painless, also.  [[User:KP Botany|KP Botany]] 03:51, 26 July 2007 (UTC)

==What is the American continent?==
The origins section states several times that cultivated cannas come from "The American continent". This is only made more mysterious by a link to a page on the Americas which confirms that there are two continents that make up the Americas. Which continent does the article refer to? The introduction says that the genus is native to both North and South America. Can we get a clarification on this?[[User:Ethel Aardvark|Ethel Aardvark]] 02:26, 8 August 2007 (UTC)
:Changed per your request.  Feel free to edit unusual encounters like this yourself.  Thanks for the alert.  [[User:KP Botany|KP Botany]] 02:30, 8 August 2007 (UTC)
I would have cleared it up but I was a bit confused and didn;t know enough to get it right. Actually I still am confused. The introduction says that the genus is native to both North and South America while the origins section states that "Canna is a South American genus". I assume the genus is native to both continents and we can we remove references to "the American continent" and claims that it is an exclusively South Am genus. But this is well outside my normal geographic range so I'll levae it to the knowledgeable to clear up. 
Thanks [[User:Ethel Aardvark|Ethel Aardvark]] 02:35, 8 August 2007 (UTC)
:Well, everyone else is probably confused.  I think you should just go with your gut, or your brain, and say, hmmmm, why does it talk throughout about the Americas, then leap to South America alone and just edit it.  The section is still confusing, but not for that reason.  [[User:KP Botany|KP Botany]] 02:53, 8 August 2007 (UTC)
:The section was translated from an early French book, the Americas was a common term in those days. It is right that we are more precise here. The actual range is from Northern Argenina to the southern states of the USA, taking in the islands offshore as well.[[User:Giantsshoulders|Giantsshoulders]] 11:17, 14 August 2007 (UTC)
==Canna as biofuel==
I have supplied canna rhizomes to five international and smaller companies conducting trials on various plants ability to supply energy for the future. The feedback that I have is that Cannas are the most productive producer of ethanol of all, their high starch content, the highest of all pant life we are told, means that they are in there as heavy contenders in the right climate. However, we are not getting quotable feedback on this subject. I am aware that the wikipedia statements about biofuels are unsubstantiated and I am happy to remove them from the Canna article, unless somebody thinks that we should stick-it-out until we get feedback?  <small>—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Giantsshoulders|Giantsshoulders]] ([[User talk:Giantsshoulders|talk]] • [[Special:Contributions/Giantsshoulders|contribs]]) 19:34, 5 October 2007 (UTC)</small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->

==Is there a policy about blog links?==
I recently added links to some serious blog articles that added, in my opinion, references to material that is not dealt with in the Wikipedia article. The same day, they were removed. Why? External canna links to many of the University sites are a shambles, but never questioned; these were well researched and substantiated articles.----[[User:Giantsshoulders|Giantsshoulders]] ([[User talk:Giantsshoulders|talk]]) 00:07, 5 December 2007 (UTC)
==Main photo on taxo==
This seems to be a very weak photograph of a genus that normally has people gasping for breath the first time they experience it.
Can somebody come up with a more "dynamic" photo than these 2nd rate specimens in somebodies front garden?


== Reproduction from cane cuttings? ==
Could cannas reproduce if you cut the cane and stick it back in the ground?
Are there gels/powders which might help?  <small>—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/141.149.54.245|141.149.54.245]] ([[User talk:141.149.54.245|talk]]) 03:51, 26 August 2008 (UTC)</small><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

No, all propogation methods have been tried, the only ones that work are splitting rhizomes with growing eyes, in vitro and seed.[[User:Giantsshoulders|Giantsshoulders]] ([[User talk:Giantsshoulders|talk]]) 11:31, 26 August 2008 (UTC)


==Photo not correct==
The photograph that has been inserted is firstly not a species, it is a cultivar. Changing its name is also wrong. Canna 'Pretoria' is a synonym for the Italian Group C. 'Bengal Tiger', which has green and yellow variegated foliage and an orange flower. This photo is of a Crozy Group cultivar and is obviously not correctly named, and so I have removed it.[[User:Giantsshoulders|Giantsshoulders]] ([[User talk:Giantsshoulders|talk]]) 17:13, 26 June 2009 (UTC)

I have solved the issue of the lead image by adding a photo of Canna (Italian Group) 'Italia', Sprenger 1894. This is the most historically important cultivar in the genus, and is preferable in an encyclopaedia to a pretty photo of a feral specimen. [[User:Giantsshoulders|Giantsshoulders]] ([[User talk:Giantsshoulders|talk]]) 06:13, 13 July 2009 (UTC)

:Wikipedia had problems with the Commons image for Italia, so I switched to an existing image of Canna 'Bavaria', another historical landmark for the genus. [[User:Giantsshoulders|Giantsshoulders]] ([[User talk:Giantsshoulders|talk]]) 06:13, 13 July 2009 (UTC)

:Nothing to get so worked up upon. I asked a professional botanist to id the plant and she replied that it was a canna hybrida. FYI, there is a canna hybrida, see [http://www.takii.nl/takiiseeds.php?pg=2&hv=1&pd=1&prodid=53&cat=8&scat=0&zoeken=0 here], [http://www.finerareprints.com/print_detail.html?stock_no=10923 here], [http://www.hear.org/gcw/species/canna_hybrida/ here] and [http://www.springerlink.com/content/u6l0r8163pgp734l/fulltext.pdf here]. I am replacing the image since it shows the flowers in different stages and the leaves and thus the EV is higher. --[[User:Muhammad Mahdi Karim|'''Muhammad''']][[User Talk:Muhammad Mahdi Karim|<small>(''talk'')</small>]] 15:38, 19 July 2009 (UTC)


Let's start from square one:

Do not call other users names such as you did, Giantsshoulders. I have removed that text. For now, considering the nature of your name calling, I am asking you to step away from editing this page.

Muhammad, I will ask another user to investigate the situation with the images and resolve it, and explain it to you if necessary. Thank you for keeping your cool and bringing the matter to my attention instead of excalating the situation.  --[[User:KP Botany|KP Botany]] ([[User talk:KP Botany|talk]]) 21:58, 20 July 2009 (UTC)

:My two cents about the photos.  The photo [[:File:Canna Italia 1505.JPG]] is an orange and yellow blob.  It does not show the plant; it shows a front end view of a flower with little discernible detail.  Given the choice betwen the two photos for illustrative purposes, the photo added by Muhammad is preferrable for showing more physical features of the flower and plant.  If it is incorrectly identified, that does not make the image any less valuable.  Incorrectly identified flowers can be re-examined for a correct identification.  For plants that are grown as ornamentals or for food, photos of cultivars can be as valid as a wild species, and in some cases ought to be preferred for the recognizeability of the taxobox image.. --[[User:EncycloPetey|EncycloPetey]] ([[User talk:EncycloPetey|talk]]) 18:37, 21 July 2009 (UTC)

:IMO [[:File:Canna Italia 1505.JPG]] is not immediately identifiable as a ''Canna''.  It shows a face on view of the flower with little context. Also the flower is past its prime and the plastic pots in the background detract from the image. [[:File:Canna sp.jpg]] is immediately identifiable as a ''Canna''. It has context -shows flower, buds, stems and a portion of the leaves. and has sharp focus. There had been a previous problem with misidentification of this image and the author has sought to rectify this by making enquiries,  but I think that the caption of "''Canna'' hybrid" would suffice.  Of the two pictures I believe [[:File:Canna sp.jpg]] is best suited for the purposes of the taxobox. [[User:Melburnian|Melburnian]] ([[User talk:Melburnian|talk]]) 08:11, 22 July 2009 (UTC)
*Since there is clear consensus for my image, I am adding it as the taxobox. --[[User:Muhammad Mahdi Karim|'''Muhammad''']][[User Talk:Muhammad Mahdi Karim|<small>(''talk'')</small>]] 15:34, 14 August 2009 (UTC)

==[[Canna edulis]] or achira==

I know practically nothing about taxonomy but I would like to write an article (or include in a Canna article) information about the prehistoric cultivation for food of Canna edulis or achira in Latin America.  Canna indica is apparently the accepted scientific name for achira -- but achira is commonly called Canna edulis in archaeological literature. 

So, where do I insert info on prehistoric cultivation of achira?  Do I create an article called Canna edulis?  Do I include it in the article Canna indica? Other options?   

As a comment, it seems to me that Canna edulis would be a more desirable scientific name for what is now called on wikipedia Canna indica.  The plant didn't originate in India as indica would seem to indicate. [[User:Smallchief|Smallchief]] ([[User talk:Smallchief|talk]]  12:32, 21 February 2016 (UTC)

:According to reliable botanical sources, such as the [[World Checklist of Selected Plant Families]] and the long list at [http://www.tropicos.org/Name/5800008?tab=acceptednames the Tropicos entry], the correct scientific name of the species is ''[[Canna indica]]'', regardless of what it's called in the archaeological or horticultural literature, so you add it to that article.

:The epithet ''indica'' often means "of the Indies" in the same sense as "American Indian" or "West Indies". Scientific names can't be changed, however misleading they may turn out to be. Thus ''[[Scilla peruviana]]'' does not come from Peru! [[User:Peter coxhead|Peter coxhead]] ([[User talk:Peter coxhead|talk]]) 08:52, 22 February 2016 (UTC)

== Species list ==

{{Ping|Plantsurfer}} the most recent version of the Kew database that powers both the World Checklist of Selected Plant Families and Plants of the World Online accepts only 12 ''Canna'' species. I updated [[List of Canna species|List of ''Canna'' species]] to include this taxonomic view. Even given the Tanaka list, there aren't enough in my view to justify a separate article, and I would be inclined to merge that article here. The lead could then be revised to give a species number range based on Tanaka and WCSP/PoWO. What do you think?
