Northern pepper update
It's been a hot summer here in western Canada at 53.5* north. Probably not hot by most of your standards, but most people around here don't have air conditioning since there are only a handful of hot days each year. Sure could use air this year, spending a lot of time in the basement instead. The peppers are fond of the heat though. I just have 5 pots on the deck, here's where they're at.
Here is Matchbox Chili. It's rated at 40,000 SHU, so decently hot but certainly not crazy. The plants are very productive and quite early, but the plants are small. I have two 7-gallon pots planted with these, one has 3 plants in it, the other (the one pictured here) has 4 plants in it.
Next up is a Naga that I started indoors in July 2013, had an indoor harvest in February of 2014, then kept it alive for planting out this spring. It looked really sickly in June but recovered when hotter weather arrived at the start of July. I was figuring no harvest from this one, but recently it has started setting lots of pods, not sure if there is time to ripen.
This guy is called Ring of Fire. Seems to be very cayenne-like in appearance. I sampled one green and it was much hotter than I was expecting, maybe 100,000 SHU. I'm not sure if it's hybrid or OP. The plant is healthy, I like the size for these 7 gallon pots (2 plants in a pot), and the fruit production is pretty good when you push back the leaves and look closely. A couple pods have turned red, most are still green.
And last but not least is Firecracker. I grew this a few years ago and when autumn froze me out 90% of the peppers were still green. Yet they had amazing heat, just like a Thai chili should. So I kept some seeds and am having another go. They are still in full-bloom mode and setting peppers, but the fruit set looks good so far.
