We got a lot of sunflower seed packets this year for Easter, so I figured I’d plant a few of them with the girls.
The seeds look just like the ones you eat with shells on them.
I wondered what happened to the shells when they started growing and apparently, the sunflower seed shell cracks open and the plant germinates from there:
The shell eventually falls off and you have the plant leaves starting:
Apparently, I need to be finding a place to plant these now into the ground, because they will develop large taproots and especially so since they are giant sunflowers.
Here is a good website for some sunflower growing tips.
