I need leeks, unfortunately I can't find a vendor that keeps them on a regular basis. I know I found one farm on my last character that had them, but I can't remember where it was. If anyone can point me to any free leeks, preferably ones that respawn, I would greatly appreciate it.
For some reason I seem to recall some in Solitude. If you travel from Proudspire to where the vendors are, just before you go under the arch you should see some on the left. These respawn, but it takes awhile.
Pretty sure there are some in Dragonsreach's kitchen too.
241 already-harvested leeks can be found in 94 different locations, most notably the http://www.uesp.net/wiki/Skyrim:Thalmor_Embassy (http://www.uesp.net/wiki/Skyrim:Haafingar)
3 leeks are always sold by http://www.uesp.net/wiki/Skyrim:Jala
Can be harvested from Leek plants. 170 plants can be found in 21 different locations, most notably http://www.uesp.net/wiki/Skyrim:Battle-Born_Farm (http://www.uesp.net/wiki/Skyrim:Whiterun_Hold) and http://www.uesp.net/wiki/Skyrim:Loreius_Farm (http://www.uesp.net/wiki/Skyrim:The_Pale)
This vegetable is less common than the other fruits and vegetables because it is not in the leveled lists used to generate the contents of random food containers (Barrels and all varieties of Sacks)

LOL, Leek locations should be a page on Skyrim wiki.
D'oh ! Must be remembering finding grilled leeks in some of the bandit caves (although those are on the table and not in barrels). I usually grab the raw ones whenever I come across them so I can make soups.
I hoard leeks, too. Like people said, all the farms have them, and they should respawn every in-game month or so. Check the kitchens in Dragonsreach and the other castle kitchens.
Since leeks generally grow alongside potatoes and cabbages on farms, I often find tomatoes the hardest component to find for my soup. At least tomatoes can turn up at random, though...
