message: I wonder whether this article should mention that "Lamb's lettuce" is not, strictly speaking, a true lettuce, as it belongs to a totally different plant family to familiar varieties such as iceberg? Also, is Chinese leaf really a form of lettuce? I would be interested to hear whether any one can clarify for me whether this, as with other lettuces, is a member of the asterale family (compositae), or belongs (as I seem to recall hearing) to the family of crucifers.

replies: text: Maybe he got attacked by a lettuce as a child LOL - after being around here a while - I still fail to understand why people vandalize. The ones I expect are immature kids vandalizing "dirty word" articles, or adding "dirty words" to articles, or messing up the school page, or making nasty remarks about their teachers, or defaming their friends.

message: The article mentions lactucarium, an opium-like substance found in lettuce. Is this in common (I'm in the US) salad lettuce like Romaine and iceberg or only a few species? — Sam 23:36, 26 March 2007 (UTC)
replies: text: I think this is found in "wild lettuce" (Lactuca virosa) not the same as commercially available lettuce. It grows as a weed in North America. Badagnani 21:07, 18 May 2007 (UTC)
replies: text: Although the standard definition of lactucarium requires its production from Lactuca virosa or "wild lettuce", it was recognized that smaller quantities of lactucarium could be produced in a similar way from Lactuca sativa and Lactuca canadensis var. elongata, and that lettuce-opium obtained from Lactuca serriola or Lactuca quercina was of superior quality.

message: I know this is a place to discuss the article, not the subject, so I guess I'm skirting on the edge of both here, but: I came here to find out what the "green leaf lettuce" I see in American supermarkets is, and discovered that this article mentions nothing about it. Google has provided me with only very vague results (nutritional information, but not whether it is different from or the same as Romaine, and so on), so I'm wondering if anyone more educated than me could clarify this, and perhaps take the opportunity to improve the article?

message: The article says that lettuce is "hardy to zone 6". Since lettuce can be grown in much colder zones, I assume that this refers to winter hardiness. Since the plant is almost invariably grown as an annual (does it even have perennial behavior?) is this relevant, and is it important enough to be so high in the article? I'm deciding not and moving this fact lower in the article, but wanted to ask the question.  RamblingChicken (talk) 23:29, 4 June 2011 (UTC)
replies: text: The criterion for inclusion on WP is verifiability by reliable secondary sources rather than truth. We have to go with what the sources say even if we personally disagree. In the absense of reliable sources it should just be left out. I hope this helps.--Charles (talk) 10:00, 5 June 2011 (UTC)

text: RC has a point. The term is vague because it is used in different contexts. According to my childhood instruction, it means that the plant can survive frost; "half hardy" would mean that it can survive frost as a mature plant, but not as a seedling. This should be clarified in text, or it would amount to hand-waving. JonRichfield (talk) 15:13, 10 January 2012 (UTC)

message: I have removed the claim that "Christopher Columbus introduced lettuce to the New World. It seemed suspicious and the source is lightweight to say the least. I found hardly better sources claiming (without support) that he did so on his second voyage. I found nothing to support the idea that if he did, the crop was established from that point on. I have no access to primary sources or even to authoritative secondary sources, but in searching online, I found nothing pre-twentieth century, and nothing substantial post 19th.

message: Lettuce contains several defensive compounds, including sesquiterpene lactones, and other natural phenolics such as flavonol and glycosides, which help to protect it against pests; certain varieties contain more than others, and some selective breeding and genetic modification studies have focused on identifying and producing varieties with larger amounts of these compounds for increased pest resistance.[36]

replies: text: The source says "The resistance seems to reside in the latex.

replies: text: If they're trying to transfer this to commercial varieties, they're trying to produce commercial varieties with larger amounts. I've tweaked the sentence a bit. Dana boomer (talk) 14:08, 9 September 2012 (UTC)
replies: text: No, that is not the only means of increasing the resistance, adding larger amounts, the scientists.could, as in the cases of other plants, add the generic resistance to different locations, tweak the molecule to make it more powerful and add lesser amounts, this is original research on your part, an assumptiom that increased insect resistance is always due to larger volumes of insecticides. That is not how it works, and it is not how it is always done for very obvious reasons. Eau (talk) 15:33, 9 September 2012 (UTC)

replies: text: First, your dictatorial manner does not make for a collegial editing environment. Second, please don't add major cleanup banners to featured articles when you only have an issue with one word in the entire article. The cycle is bold, revert, discuss, not bold, revert, slap an even bigger tag on the article. The Asteraceae article itself says that the inflorescence is "generally referred to as flower head" - if you would like to change "flower" to "flower head", that's fine, but I see no reason to use a term that many readers won't understand - especially when the source doesn't use that term. And yes, when an editor wants to change information that is already reliably sourced, it is upon them to find new sourcing, not to demand that others do so.

message: Because of the lettuce shortage, KFC is using cabbage in place of lettuce, so when I saw the Wikipedia article locked due to vandalism, I thought I should mention though officially here in Australia where we have some Yazidi, the Sydney Morning Herald does concur that Yazidi don't eat lettuce, for cultural reasons, but then say "The sect lacks any written text, which helps account for the tall tales explaining its doctrines." Which AFAIK they do have their own Bibles, but the Wikipedia article on Yazidism (which isn't locked due to vandalism like the lettuce article is) mentions 'cabbage' "Many Yazidis consider pork to be prohibited. However, many Yazidis living in Germany began to view this taboo as a foreign belief from Judaism or Islam and not part of Yazidism, and therefore abandoned this rule.[72] Furthermore, in a BBC interview in April 2010, Baba Sheikh, the spiritual leader of all Yazidis, stated that ordinary Yazidis may eat what they want, but the religious clergy refrain from certain vegetables (including cabbage) because "they cause gases".[73]"
