This year's most hardy tomato award goes to Wapsipinicon Peach! These hardy souls weathered several frosts until finally succumbing to 3 nights of freezing temps. December 6th RIP!
Here in Orange County, CA the last two standing out of 26 varieties I planted were an Opalka and a Black Cherry. They have survived a week of 35 to 38 degree night time lows. Even though it still had green foliage on it and still had tomatoes on it I pulled the Opalka yesterday, and will pull the Black Cherry today even though it still has green foliage and some green tomatoes on it because I have no hope of them ripening with this unusual cold spell we have been having. The partially ripe Opalkas still tasted good, but the partially ripened Black Cherries had a terrible taste.
I don't know what variety I have out there. Pulled all the markers when I thought I was going to yank the plant back in July. Decided to keep it along with a few others. The others succumbed to winds from TS Lee in September. The one that remains is a beefsteak ... probably Beefy Boy or Church. We had lows in the 20s & 30s for about a week, so I covered it and stuck a light in the cage. I see blush on one of the tomatoes today. Would love to have a fresh tomato for Christmas.
