Here is our primary Jalapeño plant; we have two plants but this guy here is definitely the largest. He is 15″ (40cm) tall from base to highest leaf. Typically Jalapeño plants will grow to be about twice that height, so my little guy is only a teenager. The plant is often called an annual, however if kept in ideal temperatures (not exposed to frost) they will keep growing and producing.

Over the last couple weeks our Jalapeño plants have been flowering. Since we are growing indoors with no bees or insects to pollinate, I have to do it myself. An old toothbrush head on the electric toothbrush really helps save the day; the vibration is just enough to get the pollen shaking loose.

I aided this guy by very gently removing the old petals; only a couple petals were left attached, and the fruit was mostly visible. You can see some of the left over pollen on the fruit. Each fruit appears to be about 1.5-2cm in size (0.5″ give or take).

We have multiple fruit starting to appear. I count four peppers so far, with several older flowers that are beginning to bulge. I don’t want to go disturbing the flowers yet in case I break them off, or ruin the chance for them to bear fruit.
