Has anyone grown a shiranui sumo citrus? Is it very cold hardy?  If so where did you purchase it?

I have a large in ground tree growing inside a heated greenhouse in Colorado.  Probably as cold hardy as a mandarin.

Shiranui mandarins are def a high quality fruit for flavor. I posted some pics of the fruits i got this year in the general citrus threads. I would say citrus as a whole is pretty cold hardy with most types being able to take into the low 30s.

Shiranui (Dekopon) is said to be hardy down to -10°C. I have a tiny plant in a pot and cannot tell from my own experience

My in ground shiranui lost 70% of its height last winter when we went to 14 degrees one night in March and I think my heaters l’un cold frames didn’t come on. It came back to three feet high this year but again, I went to 8 degrees for two hours with no electricity so no heaters, then next day 2 degrees and below freezing temps for almost a week while I was on vacation in Fl for a week. The shiranui looks bad again but trunk still green above graft line. The fruit doesn’t ripen until January commercially. I have one in a pot that I brought inside my house during the single- digit nightmare week, and it has one large green fruit on it now. Stuff ripens late for me here.

Very interesting and beneficial Citradia, to know of such Cold hardiness, still on search for Shiranui for taste but very good ad on the cold hardiness also for my climate  8)
