It starts out as this amazing little star shaped flower.
Then the base of the flower seems to EAT the flower petals. :)
Soon, all the flower petals disappear inside what now looks like a little closed up lantern.
Then the lantern swells!
The flower inside turns into a tomatillo fruit! You can peer into the hole on the underneath side and see a smooth green tomatillo forming inside its little lantern. :)
By the way, I searched the web for the correct terminology for these stages of growth, but found nothing. So, you'll just have to make due with my layman terms. The "lantern" is actually the husk. I DO know that. :) But lantern sounds better if you ask me.
