In the Olympia-Tacoma-Seattle area in WA state there are many anecdotal reports about Meyer lemon trees in containers up against a house being able to survive some Winters. A typical Winter will get down to about 15F for just two nights, and it might be one or two degrees warmer in a specific area or near a house, so interrpret that however you will.Protection from wind might be a factor as well.
In Europe we have a lemon variety that is present in Czech collections and distributed previously under Yuko name. I suspect that it is some sort of lemon hybrid either with Yuko or ichangensis. A small plant grafted on FD roots survived in my garden a very harsh winter with strong winds, night temperature up to -9.6C and frozen ground. Some twig damage was there, but a plant recovered perfectly. Same winter I had some stem damage at Yuzu tree.It is not a strong grower,but fruits are small but have a taste and a smell of regular lemons.They are ripe by November.
It seems like no body have heard of Harvey Lemon. There were also very limited info about this variety. Some one claimed that it is far more cold hardy than meyer lemon, but why and how??? Did the normal lemon tree mutate its own gene by chance to tolerate colder climate?
It is deffinitely not a trifoliate hybrid nor Ichangensis papeda hybrid.

I believe most of them are lost now.
Hey ilya do you know where this lemon is sold in europe?
Fruits in November 2017:
Here is my Harvey lemon. It was a lot bigger but I Ieft it out in its pot to test how much cold it would take totally unprotected. It saw 23 then 22 degrees a couple nights in a row in its pot, died back nearly to its roots but is coming back strong. It probably would've taken the cold better if grafted and planted in the ground. Im assuming it may be just as hardy as Meyer lemon or a couple degrees more hardy.
Yes, I forgot to mention my tree is a rooted cutting.

Adavo should restock in a couple of months maybe i can find it there?Zdenek surely hasn't it on his catalog of available plants now; hopefully it is still in business, since i sent him 60€ last monday to get some plants!
