I had some Ichangstar60 seedlings, most of them died but about 3 or 4 are coming back from the roots after 4 days below freezing and a low of 9F.
That sounds good, frost hardiness also should get a little better with age and size.
I have a 2 year grafted ichangstar 60 on PT which gets in ground the bext days. Im very excited how hardy it will be compared to my other in ground citrus hybrids.
Did all the seedlings survive or did some freeze to death?
Cold Hardiness results, low of 9F. -13C:
Dead
Bloomsweet High grafted and some poncirus growth allowed below.

Bishop 852
Bishop Citrandarin, possible progeny of 852 Citrandarin. This tree is grafted onto Poncirus and has only been field planted since last Summer. The tree was exposed to prolonged to 2°F temperatures accompanied by high winds. The tree exhibits obvious damage, but appears to be recovering. The original tree was planted and fruited by Hardy Vermont.
Well My zone 7 experiment failed. Arctic Frost, Orange Frost, and Bumper all succumbed to this years winter. I thought they could male it unprotected but alas they are dead to the roots.
Oh that s a pity, but I wouldn' t say failed, the first try failed, there are still a lot of varieties worth for a try in zone 7, though not all have very good fruits. But I think Prag Citsuma, and Carolina lime from Stan Mc Kenzie nurseries should be very frosthardy and have good fruits.
My Prag Citsuma survived very good 3 winters down to -16 ° C. The only protection was a frost cloth, espeacially for night frosts with day sun in spring.
Have good luck.
