Another fun fact about plant naming conventions: all lettuces* are the same species
*except wild lettuce but nobody really considers that a lettuce. Still, I guess it would be more correct to say all of the food lettuces are the same species.
Irrelevant side quest that I went on while double checking this: DuckDuckGo now forwards some search queries to their chatGPT wrapper, which prompted (pun intended) the following interaction:
More powerful AI says:
No, not all lettuces are the same species, although many commonly consumed lettuces (e.g., iceberg, romaine, butterhead, oakleaf, and leaf lettuce) belong to the same species, Lactuca sativa.
However, some plants commonly called "lettuce" belong to different species or even genera. Examples include:
Lactuca sativa: The typical garden lettuce varieties (iceberg, romaine, butterhead, oakleaf, loose-leaf lettuces).
Lactuca serriola: Wild lettuce, an ancestor to cultivated lettuce.
Valerianella locusta: Corn salad or lamb's lettuce, commonly consumed as lettuce but from a different genus.
Cichorium endivia: Endive, sometimes called lettuce but technically not in the lettuce genus (Lactuca).
Eruca vesicaria (Arugula or rocket): Often mixed with lettuces but belongs to an entirely different genus and family.
In summary, while most common lettuces belong to a single species (Lactuca sativa), not everything commonly called lettuce or used similarly in salads is botanically the same species or even genus.
Are those actually considered lettuces, though? It's most likely a cultural thing but none of those are lettuces over here. As in, calling them lettuce would be as far fetched as calling spinach lettuce.
It's a bit clearer in french; "weed" is "mauvaise herbe" which literally translates to "bad herb/grass".
My co-workers call me weed I think it's because I'm tenacious. So much in fact I have a meeting with HR on Monday probably a pay rise
Fun fact: the name for a weed in my native language is literally "angry grass" :3
Unkraut in German. Doesn't deserve to be called a Kraut.
Similar in Norwegian: Ugress. Un-grass.
I've heard one definition of it that I like: The grass that your (grazing) animals won't eat.
How about honeysuckle vs trumpet vine? Both grow like hell, invasively, where I live. One is a tasty and pleasant treat when flowering. The other is just.. there, growing. A lot.
Same rules apply. If you don't want it there, it's a weed. If you don't mind it being there, it isn't.
i call this the weed paradox.
even though weeds grow unassisted. it is impossible for everyone to grow weeds in their garden. for is they try, they are no longer weeds
A weed is whatever your HOA says it is.
A HOA is a weed.
The general definition of a weed is "any plant growing where you don't want it to be". A corn plant in a bean field is a terrible weed.
what the hell is a bean field? also beans are great with corn they climb the stalks, also have squash, then boom you have the so called three sisters.
Just wait until he finds out about "tree"
Any kind of twig that's not a shrub?
My definition: aggressive spread and resilience to removal.
Plants that are pretty might get more of a 'pass' than ones which are ugly, poisonous or thorny, but ultimately, even the most beautiful flower becomes a weed when it's suddenly everywhere and you are fighting constantly to get rid of it.
aggressive spread and resilience to remove
Many would argue that mint is an herb. But if you ever had your garden invaded by mint, you'll definitely classify them under weed.
Always plant mint in a pot. And if your neighbour has mint in their garden, you better have a 2m trench filled with concrete between their garden and yours.
Weeds are just highly successful flowers that have earned resentment from others.
In Spanish we call them "malas hierbas"
In German it's "Unkraut" which could either be interpreted as "not herb", "abnormal herb" or "evil herb". Is the range similar in Spanish?
OOP is the author of something like seven published novels, one of which has been adapted into a movie and another of which may soon be made into a streaming series. Never feel embarrassed to say what you learned today.
It’s easy when you didn’t know something that is completely reasonable not to know, like in this example, but it’s always good to admit your ignorance.
am i not supposed to want weed around?
Weeds is just the gardening term for "their kind".
"you people"
My garden is all weeds. Tons of different plants, but some dominate in certain seasons, growing like 5 feet high. Seems to have avoided anything nasty though, no thistles, nettles or brambles.
My neighbour's garden is a thin layer of plastic astroturf. And they let a dog run about on it. Good luck getting dog diarrhoea out of that.
I know which I prefer.
If you are happy with the plants being where they are then they aren't weeds. The main problem is companies that sell plant killing chemicals and services treat the word 'weed' as if it had a universal meaning.
I wish someone had warned me before No Mow May about brambles.
1 shoulder injury and a year later I need chainmail gloves and a fucking flamethrower. I fill my green bin with brambles, by the time it's picked up they've grown back.
The main root is under a shed. I don't know how to eliminate it.
I don’t know if this will work on brambles, but for pesky root systems I’ve had luck with Bonide’s Stump and Vine killer. You cut near the base of one of them, then paint the exposed stem with this stuff. It absorbs into the root system and kills all of it. Works great on pokeweed.
Edit: Turns out this is just a specific brand of triclopyr herbicide like MoonMelon mentioned. So here’s another recommendation for triclopyr!
The worst I had to deal with was pampas grass, which appears to be a plant made of actual swords.
I spent three days hacking at it in a coat so I wouldn't get shredded. When I finally cut the root bulb out it was a cube of wood a foot across. I could barely lift it out, I had to roll it to the bin.
At least pampas grass doesn't spread.
The idea of “weeds” is a colonialist construct.
Yes, this was a real educational technicality fuckup, it seemed sus but everyone was like "don't you know it's a weed"? - "No, no I do not. And you don't even have a field to worry abut crop yields, it's just a lawn & now there is a flower in it, wtf."
I know it's economy (or even sociology), but it's too close to biology not to directly explain it properly.
Well, "weed" can be a legal definition. A lot of governments have a noxious weed list that either provides for consequences if you suffer that plant on your property, or just an excuse for the government to come on to your property to kill the weeds for you. For instance, Russian Olive is legally a "kill on sight" invasive plant in my area.
