same here, my over wintering plants sit in a south window, 8ft in length. suryanki cluster were first(I am picking rippened fruit still), then a super hot chili flowered and fruited(just had a small pod), next were my ceyenne which flowered and now have several pods and as I just checked appear to have several more brilliant flowers.
this has occured all winter, many of the plant's flowers were very small, pinhead size, then dropped off.
as of right now, it seems my habanero and tepin have finally fallen asleep for the winter, no new growth and the plants appear idle. hab has no new growth and the tepin lower leaves have dropped leaving only upper leaves-this has only occured in the last month or so. goats weed have grown about 2 inches in the past month. jalapeno has new growth.
I was cleaning out some old chilis from the freezer and tasted a pod that was sweet but had some heat, so I seeded a pod and planted the seeds. i now have serveral 4" plants with large leaves and small buds starting unfortunately I never wrote down the variety. with that success I thought I would plant some habanero and out of a dozen seeds only 1 sprouted to approximately 1/4" then just stopped growing, that was January. I planted some serano and only 1 sprouted and it too appears idle, it is about 1" in height and has the luxury of sitting under a grow light.
our days are getting longer and the sun is getting higher and warmer, sun is up around 8am and sets around 6:30pm(versus Decembers 9am-4:30pm). snow is melting, most of the ground is frozen solid, outside I have a south exposed flower bed, that is close to the house and sheltered and my tulips have pushed though approximately 1inch.
No suprise really, though if you want a larger plant before spring, you should pinch all buds.
