There’s also offer a 4th type available this time of year in Canada, in addition to the English cucumbers, Persian cucumbers, and field cucumbers.
Pickling cucumbers are usually roughly the same length as Persian cucumbers, but they have a bumper skin, are usually a little thicker, and they’re usually more of a yellow green, instead of a dark green. They’re closer to the Kirby ricepad is mentioning, but the ones I see aren’t Kirbys as far as I know.
It isn’t a hard and fast rule.
Tzatziki is more likely to have mint in the eastern Aegean islands.
It also varies from family to family.
Plenty of Tzatziki recipes made with mint come up online if one googles Tzatziki and mint.
Some Caciks contain dill.
Considering the population exchange that took place, it isn’t surprising that there are Turkish dishes that are identical to Greek dishes, scattered throughout the former Ottoman Empire.
Sometimes I add both dill and mint.
So does Kiki.
All the tzatziki I have eaten in my life — whether in Greece or Greek restaurants elsewhere — had dill, and very occasionally mint.
It doesn’t surprise me that some regional variations include mint, given the influence of Turkish cuisine on Greek food.
FWIW, my Palestinian cookbook only refers to mint. As does my Cypriot cookbook. And Yasmin Khan, in “Ripe Figs” includes dried mint and fresh mint or dill.
Yup. The mint seems to be the eastern influence. My dude uses it in his lamb marinade, too — that’s the Armenian in him 
And of course, tzatziki and cacık are practically the same word.
Both are very common and whichever is available is used in the Aegean islands.
I get the impression many of the Peloponnese cooks and kitchens are more rigid in the use of herbs.
The Greek Cypriot recipes I’ve seen have a lot in common with Aegean Greek island recipes, esp Rhodes and Crete
Interestingly (perhaps), in the Greek speaking part of C yprus, it’s known as talattouri, rather than tzatziki.
Interesting. No doubt they wanted to distinguish themselves from the Turkish part of the island.
Never been to Cyprus, but would love to visit some day. I have a Cypriot childhood friend who’d have fabulous recs for sure 
Oh deffo. But interesting they don’t use the Greek tzatziki.
The island is lovely - I like both the tourist resorts and the non-touristy bits. Mrs H lived there for a few years (and her younger brother was born there) when she was a young child. Her father was a soldier and was based there. The Greek independence terrorists attacked her school bus one morning - fortunately, no-one injured on that occasion - the driver took it off the road and drove through some fields to escape. But during the “emergency” nearly 400 British soldiers were killed.
Ah, nationalism. Such a useless, deadly affliction.
