It's a perennial, it'll produce for years as long as me or Gizzie doesn't kill it, but it also doesn't usually produce the first year. That's why when Gizzie killed my plants I was broken, they took a year just to grow before they produced.

I believe it is 5 gallons although it wasn't listed on the planter, it seems as big as my 5 gal buckets. It's not bigger, there's a bit of decorative facade around it that makes it seem bigger.

The species I believe is actually siling labuyo because the peppers grow pointing upwards instead of hanging down like normal. I got the seeds from my wife's coworker and she didn't know what they were so that's totally my identification but I think I'm right.
