I read that kangarhu rhubarb is good for zone 9B. They are heat tolerant I'm going to try one.

Did you actually try to grow KangaRhu? I love rhubarb but don’t want to waste my $$ if you had any advice. I’m in 9a. Thanks in any help.

Any varieties that will grow in Zone 12? I wouldn't mind trying one of the Zone 8 varieties, but I think I would have to harvest it the first year because it looks like it won't be happy without some cold. Any advice will be helpful, I miss my rhubarb dishes and it's like pulling teeth to get the stores to stock it! Thanks!

They don't recommend planting it in your climate zone.

What variety of rhubarb is best to grow as a perennial in zone 7. I tried rhubarb about 45 years ago and was unsuccessful. Reason being that the temperature in the winter wasn't cold enough in the winter and if you were to try to grow it you were required to expose the bulb (?roots) to a freeze. Are there new varieties that don't require that. Please advise.

Can I harvest rhubarb all summer in zone 3a safely? I read recently that late summer harvests are poisonous . I’ve heard and have been practicing harvesting 1/3 or less of the plant at a time. Then I wait 2 weeks before harvesting again all summer long. I have big healthy beautiful plants that are over 20 years old.
