Gerbera seeds are long and thin, with a rounded end and a pointed end. The pointed end is where the "parachute" is attached for wind dispersal. Planting advice on the Internet seems contradictory; some say plant it rounded end down, other say pointed end down, most don't mention it because they are lying horizontal in a plastic bag.
I'm using the Park Seed biodome because the sponges have a small hole in them that fits gerbera seeds perfectly - and leaves one end in daylight, which is another recommendation. They all seem to be sprouting nicely, but I frankly didn't pay much attention to up and down.
Anybody know which end is which?
