I would say hotter than a habanero but pretty close to it. As far as being unstable, grow it like you would any other pepper. Being unstable genetics just means they may look a little different than described or expected.
I grew it probably 7 or 8 years ago. Was upper heat level with good flavor and pretty prolific. Having said that, being 7 or 8 years ago, it’s likely your outcome will be different than mine because of it being a hybrid and I’m sure its genetics are still quite unstable.
Green and red Anaheim yes but the yellow and orange ones could possibly be Marconi peppers. Is there any heat to them? There are also countless hybrids out now which makes identification very difficult. It’s also common for stores to intentionally mislabel varieties and hybrids as something more...
