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.

Do you like the taste of the fruit?

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.
