To my complete surprise, after only six days in the greenhouse, seed #1 poked through the soil today! It shouldn't be long before it stands up and shows its cotyledons. Don't get too excited, it's not as dirty as it sounds... Cotyledon is just a fancy name for each of the first four embryonic leaves, or seed leaves.
This little guy's a real exhibitionist. None of the other seeds have even shown their radicles yet.
