From Elsewheres:

“The best gifts come in small packages! These ceramic EGGLINGS look and feel just like real eggs. Just crack one open, add water, and you’ve created a springtime oasis for your desk or window (even if it’s winter outside). Each comes with a terra cotta tray and seed pack. Growing is EASY — plants thrive for months in their shell and can be replanted in soil. Sold individually. ”
